I currently have Windows XP. I also subscribe to AVG. The AVG safe Search function does not operate properly now. I understand that there is a compatibility issue with Firefox 5.0. I didn't have any problems prior to this update. I paid for a subscription to AVG. I am wondering if there is any way to still use AVG Safe Search. Is there a way to go to a different level of Firefox, i.e. 4.0 or 3.0? Please advise.
