MCafee Site Advisor was incompatible with Firefox 5.0. I cannot enable it and would like to return to Firefox 4.1. How do i do that?

I was advised that Firefox could not find a compatible McAfee Site Adviser Plug in that was compatible and would therefore like to revert to Firefox 4.1 as it was before I updated. Until then I will make Internet Explorer my default browser. I loved Firefox 4.1 with the site adviser and would have kept it as my default browser.

Blocked by Mozilla due to an excessive number of crashes it was causing. McAfee id re-writing that add-on to fix the problems.
