Firefox & Thunderbird are cross-platform, making it easy to exchange Bookmarks between Win & Linux. Tabbed browsing is another reason to consider Firefox.
IE is set as default by Windows to download MS updates, therefore it needs to be left on the machine.
My biggest reason for using Firefox; it ain't Microsoft.
I was wondering if anyone out there is still using Internet Explorer. I have used Firefox since I first heard of it and tried it out. I still remember the days of Phoenix and the shortly lived Firebird. I enjoy all of the security and features of Firefox and I know there are other alternative browsers out there (like Opera and MyIE2 which changed their name recently to Maxthon). I know the people who read these forums range from those who should be commended for wanting to learn better computing practices to people who have forgotten more about computers than some of us can hope to ever learn. So I would basically like to know if any of these users are still using IE, for what reason, and what tools (if any) have kept you using IE and not using another browser.
