To re-download your add-ons, a quick work-around is to manually change your computer’s date to yesterday.

Works for Windows 10, at the very least.

I have no idea why, but this fix worked on the first attempt. Changed nothing else on my end. I only changed the date, restarted firefox, and then installed the desired addons.

Thanks for the suggestion.

edit: also on Windows 10

I get Download failed. Please check your connection for the add-on adblock plus and honey . I can manually download it and run it in debugging mode but I have to do that each session. This new updates seems to have broken a lot of add-ons.

It looks like a certificate used to sign many popular extensions expired? The verification process checks that certificate. That would explain why rolling your clock back before midnight GMT is a temporary workaround. Waiting to hear how it will be solved.
