Windows 7 64 bit. Firefox announces Add-ons disabled. Cannot "verify" them: Avast Online Security, Avast Price checker and Privacy Badger. When I try to download newest version of Online Security or Privacy Badger, I get an error message "Download failed. Check your connection". Is this Firefox's answer to the MitM critique or something else, a virus or tracker infiltrating Firefox? I did all the usual things: cleared cash, rebooted, even uninstalled and reinstalled Firefox. Now running boot scan on the PC. Making this report by mobile phone.
Any ideas? I don't like running the browser without the security and privacy working.
Cross posting to Firefox forum.
Thanks,
