How do I revert to the previous version of Firefox? I want to be able to use the MyPoints toolbar again.

I have updated my version of Firefox to 4.0b.6 and can't use the MyPoints toolbar. The previous version supported that add-on. thanks for your help.

The regular Firefox 3.6.x version should still be installed on your computer.
You can check that on your hard drive or in Start > All Programs.

However you shouldn't use the 4.0 beta versions with your regular Firefox 3.6 profile, but create a new profile exclusively for that beta version.
