My firefox updated today to latest version. As soon as I opened it, my addons were declared useless by firefox. I removed them and tried re-installing, but the site firefox sometimes says, “download failed. check your connection” even when I have a very good internet and when the extension downloads…

I am also having this problem. I’ve been thinking about switching to firefox due to problems in the browser I’ve been using for over a decade; this is not the way to encourage me. to summarize: all - or almost all - extensions have stopped working and all - or almost all - extensions can not be …

Yeah, not cool. My only - and apparently dangerous - add-ons (ublock, lastpass, and push to kindle) are gone, and as others have said, I can’t reinstall them. I’m streaming music right now so I know there’s no internet issue. Please fix this.

YEAH WHAT THE HECK MAN?! Please fix this.

Just… Blown to smithereens… (I don’t think someone’s got a time-machine stashed somewhere so we could go back and st…

Hello folks. Can only speculate as to the cause of the problem but have a workaround for you until this is fixed. Not perfect but better than nothing. Go to the addons page for the extension you need back again. Right click “Add to Firefox” then “Save Link As”, and save the .xpi file somewhere you…

Another quick work-around is to manually change your computer’s date to yesterday. This will allow you to re-download your add-ons.
