For some reason, my Firefox is now being detected as Internet Explorer 6 I only noticed because Facebook alterted me that I might want to upgrade to IE7 or Firefox. So I checked on one of those forum signatures that detect IP, OS, Browser etc. And it said WinXp, IE6. Pretty messed up. Also, when I go on Gmail, it's now set to the HTML version, so I assume this is because it sees my browser as IE6 too. I've tried reinstalling Firefox, no luck. But that was just a simple trash can uninstallation, as I noticed that all my bookmarks, settings, extensions were still there, fortunately. I believe it may be caused by a Megaupload extension I foolishly installed, from a Spanish Wii Forum (I don't even speak Spanish) - https://addons.mozilla.org/en-US/firefox/addon/3843 Although, I've removed the extension now. Any ideas? Edit - I'm running Leopard.
