Firefox Now Important Enough To Be Crummy
"We thought this was just a problem with IE. It turns out, it is a problem with Firefox as well," Window Snyder, Mozilla's chief security officer, wrote in her blog.
"We should have caught this scenario when we fixed the related problem in 18.104.22.168. We believe that defense in depth is the best way to protect people, so we're investigating it now."
Mozilla may also have another lagging security issue related to its password manager system that stores user passwords.
Security researchers at Heise Security have alleged that the password manager flaw that first appeared November 2006 and was claimed to have been fixed in the Firefox 22.214.171.124 update in February 2007 is still open.
