How to uninstall Internet Explorer 9 or rollback to Internet Explorer 8?

I wanted to try, and I installed Internet Explorer 9 and now Firefox is acting strangely. For example, the URL Windows aren't opening in time. When I Maximize Firefox the window title is blinking like crazy.

But Google Earth is acting even more strangely. The application seems to work, but when I browse or zoom Earth I immediately experience lots of blinking on my screen. How do I uninstall Internet Explorer 9 or rollback to Internet Explorer 8?

I updated to IE9 and it also caused problems on my system. Here are the steps I did to roll back to IE8:

1. Open up the Control Panel
2. Click on "Programs and Features" (may be called "Add/Remove programs" if you are using an older version of Windows)
3. Click on "View Installed Updates" in the left pane
4. Right-click on "Windows Internet Explorer 9"
5. Select "Uninstall"
6. Restart your computer when prompted

When it boots back up, it should be running IE8.

Control Panel ---> Uninstall a Program ---> Click View Installed Updates ---> Uninstall the Windows Internet Explorer 9 update.

Any following instructions should be displayed on the screen.

You don't necessarily need to. In IE, if you press F12 (Developer tools) and try different combinations from the two menus (Browser Mode and Document Mode) once the page is loaded, you can test as if IE9 is IE8.

There should be an entry in Add/Remove programs list to uninstall IE9, which will roll it back to IE8.

The correct solution is to create a new user profile for Firefox, I had this problem unrelated to IE9 and this steps fixed the problem for me. I'm really wondering if rolling back to IE8 will actually fix it for you...
