Mozilla confirms malware add-ons for Firefox slipped through
the cracks and promises to improve screening process.
Although not the most popular browser out there, Firefox - by the Mozilla Foundation - is very popular for its combination of speed, customization
(via add-ons), and a fair amount of security. That is not to say it is the most fast browser, has the best customization (which is does, though), and
is the most secure, but that means Firefox blends the three aspects together better than most other browsers. So when news hits the streets that
users may be getting infected because of Firefox... well, ya you get the point.

Recently Mozilla on their AMO blog announced that two third party add-ons for Firefox were malware infected.

Two experimental add-ons, Version 4.0 of Sothink Web Video Downloader and all versions of Master Filerwere found to contain Trojan code aimed
at Windows users. Version 4.0 of Sothink Web Video Downloader contained Win32.LdPinch.gen, and Master Filer contained Win32.Bifrose32.Bifrose
Trojan. Both add-ons have been disabled on AMO.

If a user installs one of these infected add-ons, the trojan would be executed when Firefox starts and the host computer would be infected by the trojan.
Uninstalling these add-ons does not remove the trojan from a user’s system. Users with either of these add-ons should uninstall them immediately. Since
uninstalling these extensions does not remove the trojan from a user’s system, an antivirus program should be used to scan and remove any infections.
