Have you tried reinstalling the addons? I know it's less than ideal, but on one of my installs firefox had decided to uninstall the addons after disabling them (I think because it updated firefox version after disabling them). If it did that I don't think there is any way to get them back short of reinstalling.
Yes, I installed the .xpi file, firefox still says my extensions are unsupported/unverified.
Reinstalling seems to work, but there are certain extensions that have data I do not want to lose. For example, if I reinstall ubock origin, I will lose all of my dynamic filtering rules.
Possibly you just need to force it to reverify again. If this is still the state of things try setting `app.update.lastUpdateTime.xpi-signature-verification` to 0 in about:config, and then restarting your browser.
But no guarantees. Do you have reason to believe the addons are still installed?
Yep, you're all good. I'm surprised it let you remove the fix from about:addons but I wouldn't worry about it.
That value resetting is expected, it's the time when Firefox thinks it last checked signatures, it resetting just means this convinced it to recheck as intended.
