Firefox won't load after replacing version 4 with 3 due to 4's having the effect of disabling Excel ad-ins

After upgrading to Firefox ver. 4, an indespensable ad-in for my Excel 2007 would no longer function properly (MSN Money Stock Quotes). A Google search disclosed other users of the ad-in had similar problems.

I then did a Windows Vista System Restore to a date before upgrading to Firefox ver. 4. The Excel ad-in worked fine then. Before opening Firefox, I confirmed that it was an earlier version than 4. I then tried numerous times to open it. It wouldn't open. Then went to Mozilla site (via I.Explorer) to download Firefox 3.6.17. Seemed to download and install successfully but would not open. Tried 3x's more without success.

I've tried the problem solving on Firefox support, like making sure, via Task Manager, that Firefox was not already running or not fully shut down.

Help appreciated. Thank you.
