Bug Description

Binary package hint: firefox-3.5

This appears to be similar to "489608 firefox disappear suddenly", except that that bug dates from late November, and my bug only happened recently (3 times in the last couple of weeks), involves a later Firefox revision, and the above bug seems to have expired.
It didn't seem likely that anyone would pay attention to an expired bug.

1. I was busy scrolling a web page, when suddenly it disappeared. I thought somehow it had minimized, but when I looked down, there were NO Firefox window tabs in the bottom panel (there had been a minimum of four). Top indicated no Firefox process then existed. It is exactly as if somehow the computer itself had decided to kill or xkill the process. (coincidentally(?), the previous week, Firefox had grey-screened permanently, and I had had to xkill it...)
[Temporary grey-screening for Firefox seems a lot more common lately, for some reason. ]

2. Several days ago, I had the computer up and used Firefox. I left for a few hours to run some errands, and when I returned, Firefox had disappeared. No tabs, no process.

3. Today, I was writing a letter in AOL, and was cutting and pasting something into the letter, when Firefox disappeared.
Again, top indicated no Firefox process existed. There had been six windows.

A suggestion for the previous similar bug was to try and remove some addons and see if it recurs.
Since this is a non-repeatable, infrequent situation which may never happen again whether or not any addons are removed,
the suggestion seems impracticable. Perhaps it is a generic remedy, and is suggested for all reported bugs.

To my knowledge, Firefox has never disappeared on me before the three incidents listed above. All were recent events.
I don't remember any other processes disappearing, ever before.

Could you please generate an apport crash report for this? A crash report is key for resolving your problem.
You can enable apport for one instance like this in the terminal:
sudo service apport start force_start=1

I am marking this invalid as apport will open a new bug when the crash is generated. Please include any relavant information from this report in the new bug report. If you cannot generate a crash report, you can reset the status of this one to new and we will try something else.

Changed in firefox-3.5 (Ubuntu):

I have exactly this problem. When running Firefox on the command line, the error I get is:

 firefox: Fatal IO error 10 (No child processes) on X server :0.0.

(Note that the program exited early in the morning while away from my computer.)

I also later filed a second bug report ("Firefox suddenly disappears several times lately - 2")
see: https://bugs.launchpad.net/ubuntu/+source/firefox-3.5/+bug/592597

In that, I mentioned my theory that it perhaps had something to do with low memory,
and also listed a technique I had come up with that drastically reduced memory/processor usage.
I don't know if that was the answer, but since then Firefox has not disappeared, and has grey-screened
quite a bit less.

[In case you don't look at this bug again, I will repeat myself and copy this to your new bug page.]

Hope that this helps.
