every time I navigate to a new site or page I also get additional new tabs opening which say 'Microsoft Exchange Server 2007 - this page is no longer available', so I soon end up with an extra tab every time I navigate to a new page.
so I am geting an additional unwanted MS Exchange tab/window every time I navigate to a new site or bookmark. i recentlly upgraded to Firefox 5.0 and I think this problem may have started around the same time. I also have MS Outlook but this is stand alone and I do not synch online at all, and have not changed any settings in it.

Try the Firefox SafeMode.
A troubleshooting mode, which disables most Add-ons.
(If you're not using it, switch to the Default Theme.)
- You can open the Firefox 4/5/6/7 SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
- Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.
