firefox has become really unstable - debugging is impossible. Help?
I would say it started just after the Quantum release. I use many profiles to keep activities separate, and the stability of firefox has *plummeted*i in the last coupled of months. I've tried many version of FF (Beta/Esr/Stable) to no avail.
I am using Linux(Debian Stretch) and my machine is well provisioned (256GB ram, 32 cpus), so any reason regarding resources is unlikely. I am using 50.0b9 today.
I have noticed that session management, bookmarks etc... seem to be prone to corruption. I have a profile with a *single* page open that will now not start and just crashes.
What happened to the quality control? It is frustrating as debugging is very difficult...

Are you using Sync?
Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
- "3-bar" menu button -> Exit (Power button)
- Linux: File -> Quit
- Mac: Firefox -> Quit Firefox
- Windows: File -> Exit
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- do NOT click the "Refresh Firefox" button on the Safe Mode start window
I tried using safe-mode with a number of profiles - they ALL crash without getting to the "refresh or safe mode" menu.
Somehow, firefox is completely hosed across profiles. As I mentioned before, a week ago firefox managed to delete my profiles all together, and I had to manually reinstate them.
I'm posting this using google-chrome, because firefox is completely broken and will not start. I even have it starting in safe-mode with FRESH profile, still it crashes before starting.
Again this is 59.0b9, but I have several other versions including ESR that are just as broken. I just pulled down 59.0b10, and if I "refresh" it will start, where safe-mode did not.
You should use a supported Firefox version (58.0.2 or 52.6.0 esr) and not an old Firefox 50 alpha or beta release.
Downgrading a profile can cause serious profile issues because a lot of files have been upgraded and/or replaced. You should at least create a new profile in case of issues.
The stable one and ESR crashed as well.
It would *REALLY* help if mozilla made the "refresh profile" BACKUP the session. The session is where alot of information is stored. Plugins less so.
Something is seriously broken, though I am willing to accept it could be a profile thing.
Hence, if mozilla can backup the session across refresh, it would be a safer way to maintain a large number of profiles with a upgrading browser path.
I think that Firefox should keep open tabs as part of migrating to a new profile if you use the refresh feature in Firefox.
You can copy files like these with Firefox closed to the current profile folder to recover specific data.
- bookmarks and history: places.sqlite
- bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
- cookies.sqlite for the cookies
- formhistory.sqlite for saved autocomplete form data
- logins.json (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
if you only have key3.db then make sure to remove an existing key4.db - cert8.db and possibly cert_override.txt for (intermediate) certificates stored in the Certificate Manager
- persdict.dat for words you added to the spelling checker dictionary
- permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
- sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)
