Firefox 5 got rid of my McAfee security which I need to work

more options

When Firefox 5 installed today, it said my McAfee security was not compatible, so I am left without my security. I cannot work without security, so if you cannot solve it, take away my Firefox 5 and give me back my previous edition with a compatible McAfee. Thank you

Only one silly little McAfee extension is disabled - the Site Advisor, not the entire McAfee Security suite. It is disabled because it was the #2 cause of crashes in the Firefox 5 betas; plus it has been known as problematic for some users for many years. McAfee is reworking that extension and should have a new version ready sometime in July.
