Firefox users were warned by Mozilla last week of two add-ons that had been discovered to contain malware and removed from their add-on website, but on Tuesday the company backtracked on one of those add-ons.
Mozilla said the company had worked with McAfee and determined that the Sothink Web Video Downloader is malware-free.
The initial estimate of 6,000 affected downloads has also been revised downward, to 700 downloads. Mac and Linux Firefox users were not affected by the malware discovery.
Mozilla stated that during the re-testing process that cleared the Sothink add-on, the other add-on thought to be infected, Master Filer, was confirmed again as containing a Trojan. The Sothink add-on has been re-added to the Mozilla add-on site.
