Will Firefox let me use McAffee Internet Security or should I go back to the previous version?

more options

When I downloaded the new version for Firefox a box popped up and said it would not allow my add on : McAffee Internet Security. I need to know if McAffee is working and is my computer protected. Or do I need to go back to the previous version of Firefox?

The McAfee Site Advisor add-on is blocklisted by Mozilla due to that Site Advisor extension being the #2 cause of crashing the Firefox 5.0 betas. McAfee was notified of the problem long before that extension was added to the blocklist. Now it is up to them to fix it.

I have read that McAfee is working on a re-written version that is projected to be available in the 3rd week of July.
