I'm not sure I'd put things in quite such dire terms, but I'm fairly confident that a decent number of Firefox for Windows users are rabidly anti-Internet Explorer, and would take umbrage at the very notion of Redmond monkeying with the browser in any way. Big deal, you say? I can just uninstall the add-on via Firefox's handy Add-ons interface, right? Not so fast. The trouble is, Microsoft has disabled the "uninstall" button on the extension. What's more, Microsoft tells us that the only way to get rid of this thing is to modify the Windows registry" etc. no biggie for experienced users who are aware that this has happened, but not a good advert for Firefox that it allows such a thing.. k
