Mozilla disables Password Stealing Add On Program

I wasn't quite sure if this went under "Browsers" or "Security", since it fits into both categories, I'll post a warning here too.

Mozilla has disabled and added to a block list a Firefox add-on that stole log-in information when users visited Web sites, the company says.

The software, called Mozilla Sniffer, had been downloaded about 1,800 times in the approximately five weeks it was available on addons.mozilla.org, Mozilla reported in a blog post on Tuesday.

The blocklist will prompt the add-on to be uninstalled for computers running the program. Users who installed it should change their passwords.
