Firefox has deleted all my extension data/settings after update
I just installed the latest Firefox update (67) and when the browser restarted I noticed no web pages were loading. It turned out this was because my uBlock Origin and uMatrix extensions had been completely cleared of ALL data, including their default/pre-defined rules.
All of my extensions data seems to have been cleared. The extensions are still installed, but their settings/data are completely gone.
This is EXTREMELY frustrating.
Does Firefox make backups or anything before it attempts an update? Is my extension data/settings recoverable somehow?
Come on, Mozilla, what are you doing to Firefox recently?!
Additional System Details
uMatrix uBlock Origin
- User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0
Did you check to see if they were compatible with the latest firefox version? I don't recall my updates doing that to my extensions if this was there my updates from FF57+ with the same 4 extensions would be cleared as well but they are still running and working. Besides the snafu with the addon verification in ff64 that was a bug but later updates works fine with the addons.
