Firefox closing on its own

I am using Firefox on a 2013 Macbook Pro running Yosemite 10.10.5. Every week or so Firefox closes on its own. I will be using Firefox all week and then return to find that Firefox has closed and I can't restore my session. There is no crash report. Does anyone have an idea of what might be causing this to happen and what to do to prevent it? Is there a setting that I don't know about that limits session lengths? This does seem to happen at pretty regular intervals. It doesn't happen with other browsers or applications. Thanks.

Give this a try:

You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s). Delete all sessionstore* files and the sessionstore-backups folder.

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Locate the above file. Then rename or delete it. Restart Firefox.


Don't delete the files if you need to rescue any data from them, just move them out of the profile folder to some location where Firefox doesn't look for them. You can try to read out their contents using this tool: https://www.jeffersonscher.com/res/scrounger.html
