Mozilla Bans Popular Firefox Add-On That Tampered With Security Settings (softpedia.com)

An anonymous reader writes: Mozilla has banned the popular (250,000+ installs) YouTube Unblock add-on that allowed users to view YouTube clips blocked in their country. The reason for this move is because the add-on was caught disabling a Firefox security setting (code signing) which the allowed it to silent-install another add-on, which Avast (antivirus software) was detecting as malware. Earlier in 2015, the same plugin was again caught cheating when it was using an self-contained update system that was bypassing Mozilla's add-on review process.
