i just deleted my adblock plus now i can’t even download it again- ‘download failed’
I went to “Support,” and got this:
We rolled out a hotfix that re-enables affected add-ons. The fix will be automatically applied in the background within the next few hours. For more details, please check out the update at https://support.mozilla.org/en-US/kb/add-ons-failing-install-firefox
Maybe that’ll help.
