After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

i fixed this issue, it was because of my custom config.js ... If you have a custom one - you should delete it in firefox folder, and it'll be fine

I have the same problem today for my 3 FF profiles. No option to re-enable addons and cannot install new ones. This issue doesn't resolve automatically in my case, please help!

I have the same issue after I upgraded to 99.0 (Linux 64 bit).

Most of the addons do not show any content when I click their buttons on the toolbar menu.

Maybe the issue is caused by "adguard" ad filter software, and it's ssl sites filter functions, which replaces all ssl certificates issuers to single "AdGuard"

I don't have Adguard. Same issue after upgrade ff 98.0.2 > ff 100. Rolled back to 98.0.2.

Not in my case unfortunately... Left the browser open for a couple of hours, that didn't fix the problem.
