I seem to be having access problems with Mozilla FireFox off and on. As well as not being able to access other web sites from your browser. It will not recognize some or most of the web sites that I have been using for quite some time. This happens periodically and getting worse. After checking my Add/Remove Windows Program list of Mozilla FireFox I have all of these downloads listed: 3.6.4/3.6.6/3.6.7/3.6.8/3.6.9/3.6.10/3.6.11/3.6.12/ & 3.6.13 as the latest upgraded download. Do I need all of these to function fully on Mozilla FireFox or can I remove all of them except the latest and last upgraded download? I was wondering if all of these being on computer is causing some of its problems that I am having? I have had a lot of crashes too. This has been getting worse for a month now. Any help would be great! Thanks...
