I can't log on to www.judydriscollcpa.com or get links to open on other sites.

I can't open http://www.judydriscollcpa.com or open any links on the informatist.com with firefox it seems the browser has not worked correct since I downloaded googles page rank tool. I tried deleting all my addon's setting firefox to the default browser uninstalling and reinstalling nothing seems to work. I have been suing safari because of issue and really want to get back to firefox.
