system restore to the time before you installed Firefox? Usually XP will create a restore point when you install a program.
Following an unsuccesful install of Firefox owing to something about a proxy, I'm now having an IE problem. In place of banners and ads, I get a 'The page cannot be displayed' page. I do use an ad-blocker, AdSubtract Pro, but the problem persists whether the blocker is on or off. All help appreciated. Thanks in advance.
