Firefox looses tabs on crash or End Task
Since upgrading to FF 12 I now regularly loose my tabs. When FF exits via an End Task from Task Manager or a system crash, it seems to loose the tabs. On restart of FF it coems up with the "Well this is embarrassing ..." but the list of restore windows/tabs is completely blank ! This is a complete nightmare, as I have lost months of saved up tabs and research. Please can someone help, otherwise this will be the final straw with FF which I've used since inception !

Is Firefox set to use tabs from last time when it starts up? In Options > Privacy, are you using the setting "Clear history when Firefox closes"? If so, what is checked? If you remove history on closing, you will not get your tabs back.
If you set up a collection of tabs that you want to keep, you can bookmark all tabs from the bookmarks menu and save them that way.
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

Err, the point is that I want the tabs remembered after a crash ! You are suggesting that I constantly save my tabs manually just in case ! Is this a joke. FF should just work properly, what's the point of havinga computer, if you have to do things manually !
thank cor-el
tried that, it works on the next crash, but not after that.
The only solution I've found is to have Session Manager running, seems to be working so far, but yet another bug in there somewhere that needs an add-on to fix.
Did you try to disable the Session Manager extension to see if that is causing the problem?
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

You can use the Crashme extension to make Firefox crash for testing if necessary.

Same problem here. Since version 12 Firefox has problems with Flash(on Windows, on Linux works great), you close all youtube tabs and it still plays in the background, if you close Firefox all ends. But this time, I tried to close Firefox, it imitated closing but it was still playing in the background even if I closed in it the youtube tabs, so, I checked the Task Manager's processes list and saw there firefox.exe sitting and not releasing the memory to close. I closed it manually and when I tried to reopen I lost all my tabs. Taking my 4 MB sessionstore.bak and replacing sessionstore.js doesn't work either because when I run Firefox it replaces this file with a sessionstore.js that weights about 700 Bytes and in Firefox I have only the "about:home" page. Trying to open the "about:sessionrestore" page doesn't show anything either... I found this site: http://dag.wieers.com/blog/what-if-firefox-loses-your-tabs and in the comments this Python script: http://jacaranda.org/firefox/fixstore.py but it doesn't work for me with Python 3.2. I think that Firefox should have by default something like that.
