Firefox 5 installed. Incompatibility box stated it is not comparable with my McAfee SiteAdvisor (which I depend on for security when I go on line). I did not see, at that point, a means of canceling the download. How do I get rid of this Firefox 5 and reload my old Firefox 4 so my online security (via the SiteAdvisor) can be restored? Thank you.

The McAfee Site Advisor 3.3.1 extension was the number 2 cause of crashes in one of the Firefox 5.0 betas and Mozilla Blocklisted it. That extension is disabled in Firefox 5, Firefox 6.0beta, and Firefox 7.0alpha versions. McAfee is working on a new re-written version of the Site Advisor extension to fix their problems - ETA is mid to end of July.

Not advisable to go back to 4.0.1 as 5.0 is partially a security update in place of 4.0.2.

Until McAfee gets up-to-speed, a great free alternative to Site Adviser is
