Installed Firefox 3.6.10 now my mouse wheel doesn't scroll

more options

I just installed FF 3.6.10 update, and now my mouse wheel doesn't scroll. I checked my mouse settings, and all is correct. Mouse wheel scrolls in non-Firefox applications, including off-line folders and online IE. Mouse wheel worked fine with last version of FF. Also tried hooking up a different mouse, (an old mechanical one at that), same problem. If this cannot be fixed, how can I uninstall the latest update and rollback to the previous version?

Thanks, that helped. I hate Logitech, but they are pretty good for the price. I also found this:

https://support.mozilla.com/en-US/kb/Installing+a+previous+version+of+Firefox

Which walks you through how to rollback to a previous version of Firefox, which also answers one of my own questions and is therefore useful to be posted here. But be warned, the video on the site doesn't work - it freezes about 3/4 of the way through.

Found my problem...

I upgraded to 3.6.11 and my mouse stopped scrolling and I couldn't switch between tabs.

I hit control/Alt/Del on my keyboard to go to the task manager and I noticed there was an extra Firefox process running. I ended all my Firefox tasks and then restarted Firefox and everything worked.

thanks for all the tips, however none of these work. Installed 3.6.10, 3.6.11 and latest version 3.6.13 but the mouse wheel is still not working. Waiting for comment from Mozilla. If they take this problem serious, which I doubt, reading about the problem since September and 86 people who reported...

Go to tools , options, advanced, general and check the option for smooth scroll. :)
