[Feisty] Firefox crashed -- libflashplayer.so

I am doing triage

Hello zakarpatska!

I'm going to help you fill out this bug report, so our developers can fix the problem.

What version of Firefox are you using? What flash codec?

Can you run gdb (https://wiki.ubuntu.com/Backtrace) and give us a logfile?
Does Firefox (or the Gnome Crash Handler) spit out anything?

If this fails, try running firefox in a terminal by opening the terminal and typing firefox, then enter. Then, reproduce the problem. Put the output of the terminal in a txt file and attach it here.

Thanks
Plerk

Oh...
I almost forgot!
Try some of the debugging procedures optimized for firefox.
https://wiki.ubuntu.com/MozillaTeam/Bugs?action=show&redirect=DebuggingFirefox

If you have any questions, post here!

Plerk

Hi Plerk,

I've visited the pages you've linked to and I've attached a log file I generated when firefox exited. When running without gdb there is no error message from Gnome or FIrefox - Firefox just disappears.

I'm running Firefox 2.0.0.3 and the version of the flash codec I have installed is 9.0.31.0.2unbuntu1.

I also have gdb.log file but as I can only seem to attach one file to this post I'll reply to this post and attach the gdb.log file.

Hi Plerk,

Here is the gdb.log file from the Firefox crash. Please let me know if there is any additional information I can provide on this problem.

Zakarpatska

This is great.
One last thing:
Many "bugs" in Firefox are caused by the "add-on" feature. Often, its best to try reproducing the bug WITHOUT any extensions.
To run firefox with no extensions: (From wiki.ubuntu.com)

Start Firefox by entering the following command is a terminal: firefox -ProfileManager. You should now see the Profile Manager window.

Important note: From the Profile Manager you are also able to remove and rename profiles. Be very careful when deleting profiles, if you created the profile in a directory that already existed, the entire directory will be removed!

Click on the 'Create Profile...' button to start the 'Create Profile Wizard'. Click 'Next' and enter a descriptive name for the new profile. Click Finish to have Firefox create the new profile. You should now be taken back to the Profile Manager and the newly created profile should be listed. Select it and click 'Start Firefox'. Try to reproduce the bug with this new profile.

Note: you can go back to your own profile by starting Firefox using the command firefox -ProfileManager again, selecting your own profile, and clicking on 'Start Firefox'.

If the bug still occurs, tell me please! I think plugins are still applied under a new profile.'
However, I am pretty sure running in "safe mode" (firefox --safe-mode) disables all plugins, add-ons, etc.

Thanks for your cooperation.

Hi Plerk,

If I run firefox with the --safe-mode switch or with a new profile the result is the same. When playing back the video clip mentioned in the intial bug report I get the following output in the terminal window:

Thank you elakug for triaging this report. But please, when triaging
mozilla related crashes, please follow the hints on [1]. We cannot
confirm yet this issue. Indeed it seems to be related to adobe's
flashplugin-nonfree which we can do anything about it, since it is
closed source. So Zakarpastsk might want to report it upstream
directly.

I cannot reproduce the crash on the provided link using flashplugin-nonfree 9.0.31.0.2ubuntu1 (Shockwave Flash 9.0 r31) on feisty.

Cannot reproduce on edgy:

dpkg -l | awk '{if ($2 ~ /^firefox$|^flashplugin-nonfree$/ ) {print $2" "$3}}'
firefox 2.0.0.3+0dfsg-0ubuntu0.6.10
flashplugin-nonfree 9.0.31.0.1ubuntu1~edgy1

After upgrading to 7.04, I've been getting crashes with Firefox every time I view videos on YouTube. The crash occurs sometimes when I try to close a tab while a flash video is playing, and also sometimes when I click on a link to view a different video. When I click on a link, the browser becomes stuck on the current page and never makes it to the linked page. Iin the statusbar, I'll see "loading ad.doubleclick.ne" and it just hangs. So, I thought it was a problem being caused by doubleclick.net, and I made ad.doubleclick.net an alias of localhost. The problem persisted (although instead of being stuck on "loading doubleclick.net," firefox got stuck on some activity with youtube.com).

Hi Hilario,

Here is what I get from my feisty installation when running the command line you specified above.

dpkg -l | awk '{if ($2 ~ /^firefox$|^flashplugin-nonfree$/ ) {print $2" "$3}}'

firefox 2.0.0.3+1-0ubuntu2
flashplugin-nonfree 9.0.31.0.2ubuntu1

I'm running the AMD64 feisty installation and not the i386 one - I don't know if this is relevant but I have a second feisty installation running the i386 kubuntu installation and I never see the problem on this machine. I only see the problem on my AMD64 installation.

I get the same output.

$ dpkg -l | awk '{if ($2 ~ /^firefox$|^flashplugin-nonfree$/ ) {print $2" "$3}}'
firefox 2.0.0.3+1-0ubuntu2
flashplugin-nonfree 9.0.31.0.2ubuntu1

I'm running the the i386 Feisty ubuntu-desktop (with gnome) through an intel celeron m with mobile 985gm intel graphics hardware.

I'm getting exactly the same behavior as HeWhoE; ie, Firefox stops responding when I try to close a tab with YouTube.

firefox 2.0.0.3+1-0ubuntu2
flashplugin-nonfree 9.0.31.0.2ubuntu1

i386 Feisty ubuntu-desktop (Gnome), AMD Athlon 64, NVidia GeForce 6150 (running Beryl).

My installation exhibits the same behavior as HeWhoE and dessaya .

firefox 2.0.0.3+1-0ubuntu2
flashplugin-nonfree 9.0.31.0.2ubuntu1

HP NX6325, ubuntu 7.04 i386, xorg ati driver, no beryl, ndiswrapper for wlan.

I can confirm this error.

os: feisty (Ubuntu 7.04)
browser: firefox 2.0.0.3 (Mozilla Firefox 2.0.0.3)
plugin: flashplugin-nonfree 9.0.31 (Shockwave Flash 9.0 r31)

I think this is not a problem with flashplugin-nonfree because the same plugin works fine in Opera. I think it affects Firefox and other Gecko-based browsers.

I think some people have already raised this bug in Bugzilla (https://bugzilla.mozilla.org/show_bug.cgi?id=378400). Although I can open the page (flash) described in that bug report, all the symptoms look the same. Firefox hanging when browsing Flash pages.

Thank you all for your comments.

Please all of you that are experiencing the same behavior (I confess that I'm unable to reproduce it myself :-P ), can you attach to [1] either the full crash report from /var/crash/ (if any); or a gdb retrace as explained at [2] or [3].

Thank you in advance.

In my case. it's not a crash but a hang. I'd have to kill the process manually before I can start a new instance of firefox.

I tried doing an strace (strace -p 32499) on the firefox process, here are the last few lines before it hanged.

| shmdt(0xa8fe1000) = 0
| shmctl(1075937401, IPC_64|IPC_STAT, 0xbfa56e0c) = 0
| shmctl(1075937401, IPC_64|IPC_RMID, 0) = 0
| shmdt(0xa9013000) = 0
| shmctl(1075904621, IPC_64|IPC_STAT, 0xbfa56e0c) = 0
| shmctl(1075904621, IPC_64|IPC_RMID, 0) = 0
| semctl(12779521, 0, IPC_64|IPC_RMID, 0xbfa56e58) = 0
| close(95) = 0
| futex(0xaac0bcec, FUTEX_WAKE, 1) = 0
| futex(0xb323ebd8, FUTEX_WAIT, 32679, NULL

It seems like firefox (PID 32499) is waiting on process 32679. Unfortunately, I cannot find more information about process 32679. It's not in the Processes tab of System Monitor. When I tried to kill 32679, it also kills the firefox process with the following entry in the strace.

| futex(0xb323ebd8, FUTEX_WAIT, 32679, NULL) = -1 EINTR (Interrupted system call)
| +++ killed by SIGTERM +++
| Process 32499 detached

Hope this helps. This is easily reproducable.

I can confirm this bug
I'm using Ubuntu Feisty , Firefox 2.0.0.3 and Shockwave Flash 9.0 r31

to reproduce the bug:
go to youtube, play any video, and clik on the "home" button (yout startpage). Firefox the freezes, and you have to kill it in order to exit.
Please not that this will not happen everytime. pretty random.

This error is reproducible for me, too :( This happens with all Flashplayers (flashplugin-nonfree, from Adobe site etc.). Only Flash7 works, but many sites need Flash9 :-(( This worked fine with Edgy (no upgrade!)

greetings

Well, after days of sadness, I have a (not THE) solution: compile your own kernel. The ubuntu-kernels all don't work (for me), but my 2.6.21 Nearly-Vanilla kernel works.

Interesting ... so you are saying that flash works if you use a
different kernel? Maybe it works if you switch back to ubuntu kernel
as well now?

what hardware specs do you have?

 - Alexander

No, it still only works with the self-compiled kernel.
AMD Athlon64 (X2)
NVidia GeForce 6600 (tried with vesa/nv/nvidia)
er....
32-bit version
hm...

greetings

Doing an strace on the firefox process after it hangs will always give you this...

| $ strace -p 6688
| Process 6688 attached - interrupt to quit
| futex(0xac041bd8, FUTEX_WAIT, 6710, NULL

I'm guessing process 6710 is the flash process/thread. So it must be that the flash process hanged and firefox is infinitely waiting for it to finish. Opera must be handling it better by not infinitely waiting for the flash process to finish.

An easy but probably not perfect solution to this problem I read about in the forums...

In your home directory, run this command:

mv .mozilla/plugins .mozilla/junk_plugins

That will effectively delete the flashplayer.xpt libflashplayer.so stored in that directory, which seem to be the problem. Once these files are out of the way, firefox will use the correct ones. (I believe the correct ones are located in /usr/lib/flashplugin-nonfree/ but I'm not 100% sure. )

I can now play all youtube videos fine in Feisty and I can stop the videos midways, hit the home button, etc all without problems. Also, I'm running flashblock extension and it works great too.

Hope this helps.

@Andrew:
Hm. This does not work for me either. Because I don't have ~/.mozilla/plugins... But there's no difference when I remove flashplugin-nonfree, /usr/lib/firefox/plugins/*flash* and install flahsplugin-nonfree...

greetings

N. Spohrer, ok, sorry to hear it didn't work.
For the record, here is the link to the thread where I first read about that approach. Maybe some more info in there will help.

http://ubuntuforums.org/showthread.php?t=340811

I'm now sure that it referrs to the used kernel. Even if I use a windows-firefox with wine, the windows-firefox crashes. Very strange.

greetings

Hello.

I get the same behavior as described by others in this thread. Firefox will hang and requires me to forcibly kill it.

For me this most often happens when switching from one video to another. But, as others have pointed out, there is also a random component to it, making it hard to predict when it will happen next.

I can also add that this is not exclusive to YouTube. I get crashes when playing flash on other video sites, and even flash based games.

I see this bug is being handled, but if I can contribute any additional information that might help, please let me know.

Otherwise I mainly just wanted to post so that I will be appraised of updates to this problem.

Thank you all for your hard work on making Ubuntu a great OS.

I have the same exact problem. I am using Ubuntu Feisty x64 with the latest Firefox.

I have tried the following:

Installed 32-bit Firefox with Flash

Installed 32-bit Swiftfox

Used the wrapper to install flash on the x64 Firefox

Reinstalled Ubuntu Feisty (Three times).

Deleted my profile (Several times)

Removed all extensions

Searched for duplicate flash installations (there were no duplications)

Followed the Mozilla troubleshooting guide

Tried Firefox in a terminal window (no errors)

What ends up happening is that Youtube will randomly crash the browser and I have to kill the process to get out of it. This happens one out of every five videos I view. I could stop the video, click on another one, pause it then click on another one, exit firefox completely, but no matter what you try it WILL crash when it wants to.

This happens on other sites as well. I list Youtube only because I frequent it quite a bit. I watched a video that I found on www.korn.com and it froze when I tried to navigate away from the page.

This is probably the most annoying bug I faced yet. My theory is that Adobe released a beta flash plugin as final.

It's either we make Adobe fix its plugin or fix Firefox to handle defective plugins better (instead of just hanging). I say we do both with a little more weight on the latter.

I am also someone experiencing the problem of browser freezes when navigating away from flash pages, or closing flash pages.

One thing I found through trial and error was that the freezing problem went away when I disabled my onboard sound chipset, making me wonder about the audio driver, alsa, flash, or some interaction therein.
I posted this in a thread on the ubuntuforums and someone else with a similar sound chipset reported that when they disabled their onboard sound and used a standalone sound card instead their freezing problems stopped as well. The thread in question is here:
http://ubuntuforums.org/showthread.php?t=340811&page=3

to the other people here experiencing the freezing problem, I am curious to know what sound chipsets you have, and if disabling the sound chipset, either through the bios or other means, causes this problem to stop. Obviously disabling sound isn't a solution to the problem but it might help narrow it down.

my sound chipset is a "Realtek ALC888", aka "realtek hd audio", the other person who determined their flash freezing was sound related also reported having a "realtek hd audio" chipset

if I issue the command:
aplay -l
I get the following identification:

This sounds possible. I have had some audio driver issues, and I have a

I seem to have fixed the hanging problem by using the older kernel instead of the one that comes with Feisty. In the boot menu, select kernel 2.6.15-27-386 instead of 2.6-20-15-386 and firefox will not hang while browsing pages with flash media (like YouTube).

Now, does this mean the bug is with the latest kernel and not with firefox or the flash plugin?

I don't know anything about sound drivers under Linux but it appears that Dave M G, HeWhoE , and myself all are using "hda intel" sound drivers

mine are listed as "HDA NVidia" using the aplay -l command but it is an intel board, and if I issue the command:
lspci -n

and paste the results into this page
http://kmuto.jp/debian/hcl/index.cgi

I get

I seem to have the same on-board sound card:

It came with my Asus M2NPV-VM mother board.

I am still experiencing the crash with the newest kernel, you may want to make sure you don't have flash loaded in the background on another browser or browser tab.

small update

adobe released a new beta version of flash (9.0.60.120)
I tested it and was still able to cause the crash discussed in this bug report

Also posters on their blog indicate that it has additional stability problems relative to the current non-beta version (9.0.31.0)
http://blogs.adobe.com/penguin.swf/2007/06/fullscreen_beta.html

This seems fixed in kernel 2.6.21/22 (as XPed by me before with my self-compiled kernel). Try the gutsy kernel.
Maybe it's a kernel 2.6.20-bug and has nothing to do with flash...

greetings

So who still sees this issue? or did the kernel update indeed cure everyone?

if you still see it: is there anyone who cannot workaround this problem by following instructions of https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/104470/comments/49 ?

@N. Spohrer
That is encouraging to hear that the issue may have been resolved in the newer kernels. The fact that it seems to only occur with the sound chips using snd-hda-intel drivers might point to the kernel, on the other hand flash is the only piece of software that triggers crashes on my system, and other people I have talked to with similar sound chipsets only experience instability when using flash. It might be some bug in one area or the other that is only rarely triggered but happens to be triggered reliably by its counterpart in this bug report.
I guess it doesn't much matter at this point assuming it has been fixed in a dependable manner, the only downside I see is now the response to people with this bug will be "well it's fixed in the beta" meaning they will have to either use a pre-release version of Gutsy or live with crashes until October. Which I admit is a lot better than nothing.

@Alexander Sack
I still experience this issue with the 2.6.20 kernel, I have not yet tried any 2.6.22/Gutsy kernels that N. Spohrer mentioned.
The workaround of having flash loaded in the background has been effective for my setup and other machines I have tried it on that are experiencing this issue. Unfortunately it's not a practical workaround if you are trying to deploy Ubuntu in a lab or office environment setting.

I would like to add that I have this problem on two computers, my desktop and my laptop. Both of them use snd_hda_intel. My other computer that doesn't use snd_hda_intel doesn't have the problem. The problem appeared with kernel 2.6.20.5-16.29. Reverting to 2.6.20.5-15.20 definitely fixes the problem for me.

This is a major issue, as most web sites containing flash cause firefox to hang when navigating to another page.

new workaround: http://ubuntuforums.org/showthread.php?t=511974

had the same problem with debian. my solution:

uninstall any current flash package (flashplugin-nonfree or flashplayer-mozilla)

get latest version (with MPEG4-AVC support) from adobe-labs:
http://labs.adobe.com/downloads/flashplayer9.html

i got the rpm and converted to deb (sudo alien flashplayer9_install_i386_082207.rpm)
installed it with "dpkg -i flash-plugin_9.0.60.184-1_i386.deb"

no more hanging problems so far... :)

greetz

forgot to mention:
"sudo /usr/lib/flash-plugin/setup"

after installing the debian/ubuntu-package.

Did not work for me on Fiesty; firefox still hangs when leaving a page
with youtube video.

It still crashes in Gutsy, using 2.6.22-14-generic.

I too use snd-hda-intel driver.

Is there any way to escalate this bug? I know that its a bug against a closed source flash driver, however in the technology world there is ALWAYS a work around that could be transparent to the user.

I had this problem also with Flash site after upgrading to Gusty. Following a suggestion found at http://ubuntuforums.org/showthread.php?p=1672572 I changed my color depth in /etc/X11/xorg.conf from 16 to 24. Now Firefox no longer crashes on Flash sites for me.

I had reduced the color depth to 16 to use Compiz I think. I had the color depth at 16 before with Fiesty while trying out Beryl or Compiz but I had no trouble with Firefox as I recall.

I have a IBM T40 notebook with VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)

I followed the directions in https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/98688/comments/44, which is similar to bugmenot's solution.

It is a definite improvement. Instead of a ~1/3 chance of crashing, it's now a ~1/20 of crashing. Still not perfect, and definitely something that would get my Mom (the test I use) immediately jumping back to Windows, but progress none the less.

Is there a bug tracker for this on Adobe's site? Anyone contacted them and asked about it?

I also have the same crash closing flash-pages. My workaround is simple and transparent. make a wrapper to launch firefox with this lines:

#!/bin/sh
export LD_PRELOAD=/usr/lib/firefox/plugins/libflashplayer.so
firefox $@

So, you preload de flash plugin before launch firefox and it isn't never unloaded when you close a flash page.

Of course the path of libflashplayer.so must be the one matching your system installation.

It seem to be a good workaround until the resolution of the bug.

Regards.

The bug seemed to disappear (or at least manifest far less often) when
I switched from 32-bit Feisty to AMD64 Gutsy. Maybe the bit of
indirection created when 64-bit Firefox has to use the plugin wrapper
to handle the still 32-bit Flash plugin makes the bug stop
manifesting.

I've been using the latest flash-plug available from Adobe (9.0.115.0), and it seems to be working perfectly. It's only been a few days, but no crashes so far. Also, why aren't these two bugs combined?

Same (?) bug: <https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/98688>

My fix (?) instructions: <https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/98688/comments/50>

Please disregard the previous comment. The updated flash-plugin only reduces the frequency of the crashes (to ~1/70). A step forward, but still a critical bug (see my comments on bug #98688).

I can confirm this bug with a fresh new Gutsy install with firefox 2.0.0.11 and Shockwave Flash 9.0 r115
firefox will freeze randomly when accessig a site with flash animation (example: youtube).
I had exactly the same bug using feisty.

I just did a clean install of Hardy Heron 8.04 beta. Haven't had a crash yet, and I've been trying hard. Looks good so far. Will report back if I experience a crash.

Okay, some good news and bad news.

First, the bad news: Hardy Heron 8.04 beta still crashes. It's much less often, but Firefox still crashes.

Next, the good news: I found a reproducible incident. Every time I visit this site, it will crash. Please try it out and see if it crashes for you.

http://gei.portals.streamos.com/cc/channel.php?emcid=1144&empid=4923&packageid=0000?emcid=1144&empid=4923&packageid=0000

Please specify more information regarding the recent crashes (in the year 2008).

Do you have a 64-bit system or 32-bit system? Do you have an SMP system (multiprocessor,multicore,etc.)?

What is the output of the command:
uname -a

For me:

The problem isn't ubuntu, the problem is libflashplayer. As I said
months ago, preload the library and there isn't more crashes.

Jeremy LaCroix: your issue is bug 177856 (which you are subscribed to). DanielRoesler and Julien can you answer https://bugs.edge.launchpad.net/ubuntu/+source/firefox/+bug/104470/comments/86

Bug 177856 is NOT the same thing because it does not crash Firefox for
me. My bug only stops flash movies from playing. Not only that, but it
ONLY happens on 64-bit Ubuntu, and works perfectly fine with 32-bit.

In addition, other symptoms posted by other users do not match mine.

Please advise.

Also I forgot to mention, my problem seems to have started with Firefox
3 B5. I don't remember having trouble before that.

I have a Sager NP6260 laptop. 32-bit Intel Core Solo Processor Ultra Low Voltage U1400.
I am running Ubuntu Hardy Heron 8.04 beta (fully updated).
Firefox version 3.0~b5+nobinonly-0ubuntu1
Flashplugin-nonfree version 9.0.115.0ubuntu5
This bug has been plaguing me since I first started with Feisty in April 2007.

Oh, and I can still reproduce it on command with the website above. I'm not a programmer, but I can test anything you would like to try.

Bug 177856 refers to flash crashing, leaving a gray or (invisible) white rectangle where the flash content (i.e. movie) should be. Firefox does not crash in that bug. It also only exists on 64-bit SMP (multiprocessor/multicore) systems. This bug (bug 104470) is not the correct bug report for your issue.

Are there any specific symptoms which are different in your case?

As a side note, I myself have not yet upgraded to Firefox Beta 5, so I will wait upgrade other packages first, and see if the problem reappears. Thanks for the heads up.

Okay, good news regarding finding the problem that causes this bug. The problem is indeed the update to Mozilla Firefox 3.0

After reading Jeremy LaCroix's comment:

"Also I forgot to mention, my problem seems to have started with Firefox
3 B5. I don't remember having trouble before that."

I decided to test if Firefox 3 Beta 5 was causing the problem. I had not upgraded to Firefox Beta 5 (didn't check for updates), but found the update to Beta 5. I updated all other (irrelevant) packages, except firefox, firefox-3.0, firefox-3.0-gnome-support, and firefox-gnome-support. I then opened Firefox from the console (to see any error messages) and proceeded to test extensively and try to make nspluginwrapper and/or flashplugin crash. This including opening many Youtube videos as tabs, and refreshing random Youtube tabs. Firefox did slow down dramatically, and it did "freeze" for a few moments, but Firefox/flashplugin/nspluginwrapper did not crash. The Youtube videos continued to play. No error messages relevant to nspluginwrapper/flashplugin were on the console.

I then upgraded the specified packages. Once again, I opened Firefox from the console (to see any error messages) and proceeded to test extensively and try to make nspluginwrapper and/or flashplugin crash. Nearly immediately, without opening more than one or two Youtube video tabs, the flashplugin crashed and nspluginwrapper outputed errors on the console (same errors as those in Bug .

I am convinced this is evidence that an update from Firefox Beta 4 to Beta 5 caused the bug. I will look for any relevant bug reports that document this issue, which should be after 2008-04-05 (April 5th), when Firefox Beta 5 was added to the hardy as an update. Please specify if you know of any such bug reports. Otherwise, I will open a bug report if necessary.

Jeremy LaCroix, I have found your bug 212751 and unmarked it as a duplicate of bug 177856. That is the bug report I will place future information about this bug. Thanks.

The main reason why I think this bug is different is because the
original bug has to do with Adobe's Flash plugin not working correctly
with onboard audio, and I do not use onboard audio.

I can confirm this is happening on my 7.10 laptop. I'm running firefox 2.0.0.13+1nobinonly-0ubuntu0.7.10 & flashplugin-nonfree 9.0.124.0ubuntu1~gutsy1. Any attempt at opening a page with a flash video crashes firefox. Uninstalling flashplugin and downloading the vanilla 9.0.124 plugin from Adobe fixed the issue.

Can confirm on 8.04 Firefox 3 beta 5 flashplugin-nonfree 9.0.124.0ubuntu2

Ok, I just wanted give an update for flashplugin-nonfree 9.0.124.0ubuntu2. Firefox no longer crashes with the reproducible incident I listed before. I very rarely encounter crashes anymore, maybe 1 in 500. I think Adobe has been improving their code, but we have no way of knowing that. Anyway, hope everyone else is experiencing fewer crashes!

Daniel: I can confirm that the site you have posted crashes my Firefox in about 50% of cases. I attached output from console. I'm using Kubuntu 8.04.1 with Firefox 3.0.1 and Flash 9.0 r124.

Is anyone still getting this error in Intrepid beta? I haven't seen it occur yet.

I haven't had this problem in Intrepid for a very long time. After recent updates, this bug is back and worse than ever. Every other flash video I view is a grey box, and I have to do "killall firefox" and then restart Firefox and restore the session to start seeing flash again.
