after upgrading firefox it gets hung up on checking for compatibility add-ons and won't run

I still can't find an answer on any of the support forums and no one helped me when I asked yesterday, is there anyone that may have a clue as what I can do to fix this?

I updated my fire fox on my MAC OS X to 3.6.6 version of firefox, everything went smooth till I open FireFox then the window firefox update opens up and about 1/3 through the process it gets stuck on Checking Compatibility of Add-ons and doesn't go any further. I have hit cancel and firefox opens but it doesn't open any web sites. I have removed firefox and re-installed and it is still doing the same thing. I have also let it run over night thinking it may just take a while and it never progresses, please advise, I am new to MAC but FireFox is the only browser on my mac that will open one of my business pages, known issue with mac for this company.

This happened

Every time Firefox opened

upgraded

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry. See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.
