How do I manually uninstall 3.5.6? Each time I attempt to upgrade to 4.0 the install program asks me to reboot which I have done numerous times. Add/Remove Programs prompts the same message when selecting "REMOVE" option.
Attempting to upgrade Firefox from 3.5.6 to 4.0 but it prompts me to Reboot to finish install. Rebooting PC does not resolve the issue. I get this message when attempting to remove via Windows/XP Control Panel "ADD/REMOVE" programs and if I attempt to execute "FIREFOX 4.0 SETUP" program.

The easiest way of doing it is to click Help | Check For Updates. The first time you do it, it will upgrade to v3.6.16. So you'll have to repeat the same steps to get to version 4.0.
Try to delete the Firefox program folder manually if updating and uninstalling doesn't work.
Do a clean (re-)install:
- Download a fresh Firefox copy and save the file to the desktop.
- Firefox 4.0: http://www.mozilla.com/en-US/firefox/all.html
- Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
- Do not remove personal data if you uninstall the current version.
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
