I'm afraid I know nothing of how a MAC works so you would have to contact Technical Support Chat on that issue. There is no need to remove anything as the plug in will activate again once it is updated to a compatible version.
On my Intel Mac, I went back to Firefox 3.6.19, that way I can keep using the Site Advisor plugin until the Firefox 5 issues get resolved. Also, if you aren't using K-9 content filtering, you can also get the AVG Link Scanner (similar to McAfee Site Advisor) which also works on Safari and Firefox.
How I uninstalled Firefox 5 was to do a search for any folders named 'Firefox' or 'Mozilla'. Then delete those, and download the 3.6.19 installer. Haven't noticed any security problems so far...
Over on this forum they are saying Site Advisor 3.4 now works with Firefox 5. I haven't tested it at all, though.
I have SiteAdvisor 3.4 beta working in Firefox 5.
You can download it here: http://sadownload.mcafee.com/products/sa/beta/saSetup.exe
Thanks for providing the link to SiteAdvisor 3.4 beta. I downloaded it but it's taking forever to install. It says "Please wait while we install your software" and the circle spins but nothing else happens. It has been doing that for 10 minutes now and I don't think it should be taking this long, especially for an approx. 7 MB file.
It works for me OK. What browser are you using? Save it to your desktop or a folder and then right-click > Properties and click Unblock (if present).
It should then work.
It's also sasetup.exe not sainst, so something is wrong there.

I have applied the install. SiteAdvisor shows up as a plug-in in FF5.0, but it does not have a button to check sites and does not show ratings in Google. Am i missing something?
Are you using the beta version I posted above?
