unable to install add on
I had to reinstall my antivirus (Gdata), since this all my add ons are not working. I tried to reinstall, but did not help. Then I reinstalled firefox completely, but now I can not install any add on (lastpass, ghostery, belgium eid). Or I get the message : add on is corrupt. Or I get the message: no connection When I swith off Gdata, also then I can't install add on. Win 10 - Firefox 66.0.3 (64-bits

This Add-on problem seems to be on all 52...66 Firefox versions. You can not install any Add on from web, and not even from your own hard disk.
I found a stupid, old-time work-around to this problem, but at it works and solves this immediately.
Turn your computer clock backwards some days, like May 1 2019 or something.
Then you can immediately re-install all your add-ons again. After I turned the clock back to original Date, the Add-ons still remain and are working.
I have to do some more testing, if the problem will come back. I just wanted to share my findings this far.

hi EP1952, please see the banner at the top of the support page - unfortunately there's a technical issue (an expired certificate used for addon verifications) today.
mozilla is already rolling out a hotfix for this problem, using the studies system. you can check if you have studies enabled:
- Go to [=] > Options > Privacy & Security.
- Make sure Allow Firefox to install and run studies is check marked.
if you had the preference disabled, reenable it temporarily and restart the browser. after your add-ons have been re-enabled you can disable the setting again.

I do not know how, but suddenly all add ons are working again.
