Mozilla has banned nearly 200 malicious Firefox add-ons over the last two weeks
Over the past two weeks, Mozilla's add-on review team has banned 197 Firefox add-ons that were caught executing malicious code, stealing user data, or using obfuscation to hide their source code.
The add-ons have been banned and removed from the Mozilla Add-on (AMO) portal to prevent new installs, but they've also been disabled in the browsers of the users who already installed them.
The bulk of the ban was levied on 129 add-ons developed by 2Ring, a provider of B2B software. The ban was enforced because the add-ons were downloading and executing code from a remote server. According to Mozilla's rules, add-ons must self-contain all their code, and not download code dynamically from remote locations. Mozilla has recently begun strictly enforcing this rule across its entire add-on ecosystem.
