- I updated Firefox from (67.0+build2-0ubuntu0.18.04.1) to (67.0.1+build1-0ubuntu0.18.04.1).
- Firefox crashed three times in a row.
- I launched Firefox in safe mode but it crashed too.
- Firefox begun to refuse to run saying "you've launched an older version of firefox",
Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox.
This isn't in my case.
compatibility.ini
in my profile folder was[Compatibility] LastVersion=Safe Mode LastOSABI=Linux_x86_64-gcc3 LastPlatformDir=/usr/lib/firefox LastAppDir=/usr/lib/firefox/browser
- I removed the line
LastVersion=Safe Mode
. - I launched Firefox. It opened tabs successfully.
compatibility.ini
changed to[Compatibility] LastVersion=67.0.1_20190530055249/20190530055249 LastOSABI=Linux_x86_64-gcc3 LastPlatformDir=/usr/lib/firefox LastAppDir=/usr/lib/firefox/browser
