Did you set Firefox as your default browser, or do you just use it as your primary browser? If you didn't set it as default, open Firefox and go tools->options and click "check now" under "default browser." Then say yes to making it your default browser.
If it is already set as your default browser, there are several possibilities. First, make sure you have the latest version of Firefox (1.0.5 was released yesterday), as the bug may have been fixed. Also, with a few of my programs (most notibly Konfabulator, a widget program), I had to reinstall them after I installed Firefox in order to get them to recognize it as my default browser. You may have to do this here unless someone else knows of a way around it.
Hope this helps,
John
I use Firefox as my default browser, but everytime I open anything Microsoft it opens in IE. ex. when I open MSN Messenger and click the mail tab, it opens in IE, how can I make it so it opens in Firefox instead?
