Make Firefox Look Like Internet Explorer :: Mozilla Stuff :: JohnHaller.com .
If you have more than one window open and you have Windows XP set to group similar taskbar buttons, the group will be labeled Firefox instead of Internet Explorer. This is because Windows pulls the name for groups from the actual EXE.If you're using these instructions to replace Internet Explorer with Firefox on a non-techie's computer where they don't like the Firefox interface, I would recommend not altering the Window Title or icons. That way, you can still tell which one is Firefox and which one is Internet Explorer... but browsing will feel the same.
