Mozilla has issued a hot fix for Firefox that removes the Superfish root certificate from the browser s trusted root store. The Superfish adware performs SSL interception essentially running man-in-the-middle attacks on connections to secure sites in the name of injecting contextual ads into users Web sessions. The fix won t remove the certificate if the adware is still installed on a laptop, however, as it only works if the software has been removed from the machine already.
