How do I go back to 4.0 after upgrading to 4.0.1 ?
I upgraded to version 4.0.1 two days ago. I haven't been pleased with the performance (frequent freezes, slow loading), and one of my favorite tools that I need for work doesn't work properly. I'd like to uninstall the upgrade and go back to 4.0. How do I do that?

That's not a good idea. See: Security issues fixed in Firefox 4.0.1
You can revert to the previous secure version if you wish which is 3.6.17 as follows:
- Go to Download Firefox v3.6.17 and download it to the desktop.
- Then go to Add/Remove Programs, scroll down to "Mozilla Firefox" and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
- Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox
- Finally run the installation file you downloaded to the desktop earlier.
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.
After you complete the installation, go to the Plugins Check page and update where necessary.
I would suggest in the first instance though to perform a standard diagnostic to correct the anomalies. See: Basic troubleshooting
