firefox does not restore the previous tabs after restart
After firefox Decided by itself to install the update, all my tabs were gone. No option to restore them. AND when I go to settings and set firefox to reopen to the last session it does not take it inot account. THIS for me is a definite NO. Fix it or goodbye.
Is there even a dev in this community ?! so ridiculous
The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or Firefox developers. If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.
You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s). Delete all sessionstore* files and the sessionstore-backups folder.
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
