firefox re-installs Add-ons everytime I restart Ubuntu

Which dialog is it that you actually see? Could you please take a screenshot?

Added a screenshot. Now I see, it is happening after I restart my machine (Will change the title)

That screen will appear for third party addons that are dropped in to the profile (ie, not installed via the addon manager). Did you copy the extensions folder (or any extensions) between profiles?

No, I haven't done this. I've installed them all over. Maybe it is because of the upgrade to 12.10?

I've honestly got no idea what would cause this. Nothing has changed in Firefox for weeks, but you're the second person to report this since the Unity webapps stuff landed

It just happened to me again without restarting ubuntu.
I'll patiently wait for things to get clear about this.
Thank you.

Does this stop if you disable any one of your addons?

When I try to reproduce it after disabling one of the add-ons, it asks me again if I want to install it. Should I just uninstall the add-ons one by one?

Yes please

Also, do you see any messages in the error console when this happens? (Tools -> Web Developer -> Error Console, although you might need to enable this in about:config using the preference "devtools.errorconsole.enabled")

Ok, so this is what I did:
Firstly, I removed Adblock plus. After a restart firefox asked me again if I want to install all of my extensions including ABP (although I removed it).
I removed it again and started to remove each add-on with a reboot after this. Sometimes it took me two reboots to reproduce the bug. I removed all of them except "Easy youtube video downloader".
It seems that it stopped after I removed "Https everywhere". After few restarts it didn't happen again.
I reinstalled "Https everywhere" to see if it would came back, but it wouldn't.

This are the logs from the error console:

It happened again after I installed DoNotTrack Plus.
I think it is to blame.

I am also getting this since about 1 week ago. I though my profile might be corrupt, however I have created a new profile and yet firefox still asks if I would like to install all my add-ons, each time I start firefox.

based on comment https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1058209/comments/6 , I went and uninstalled xul-ext-unity and xul-ext-websites-integration. Firefox has now stopped asking me to install all add-ons each time I start it up.

I just reproduced this issue with only *xul-ext-websites-integration* installed, so I suppose its caused by a regression in that package.

It makes sense, because we all have different add-ons, although I might say that the issue occurs when combining these packages with certain add-ons (like DNT+, in my case).

seb128 also hit this today, but I'm still not sure what's going on. Could people subscribed to this bug please set a path for "extensions.log" in about:config, so that addon manager errors get written to a file. Then, if it occurs again, can you paste the errors in to this bug (assuming that the file gets created)?

Reproduced it.

extensions.log

Ouch, that's a fairly catastrophic failure of the entire storage system. The storage service fails to initialize, which also explains the problems people are having with cookies going missing, cookie exceptions being lost etc. This must also break history / bookmarks / content preferences / form history / website permissions and basically everything in Firefox that uses sqlite.

My guess is that somebody uses sqlite before the storage service is initialized, which then causes the call to sqlite3_config to fail.

This is pretty bad, as the addon manager then deletes the database and tries to create a new one, as well as people losing data that Firefox normally saves

And thanks for the info btw :)

https://code.launchpad.net/~robertcarr/webapps-greasemonkey/fix-1058209-happy-october/+merge/127361

After some discussion with Chris it looks like this may be the safest thing to do for now.

In Tools, Add Ons, Extentions, Ubuntu related extentions are enabled, all the rest appear disabled and I am asked to re-enable when first stating Firefox after a system restart.
Screenshot attached.

This bug was fixed in the package webapps-greasemonkey - 2.3.2-0ubuntu1

---------------
webapps-greasemonkey (2.3.2-0ubuntu1) quantal; urgency=low

  * New upstream release.
    - Force initialization of storage service prior to opening
      UnityWebappsRepository (LP: #1058209)
    - Save install callbacks to prevent them from being preemptively
      garbage collected (LP: #1059441)
  * debian/patches/version_bump.patch
    - bump the version of the extension, upstream missed that in the release.

As I understand, the fix should be a part of the xul-ext-websites-integration package (because there is no package webapps-greasemonkey in synpatic) , but after an update, this package's version is still 2.3.1. Am I doing something wrong?

After latest updates everything works fine. Thank you!
