I have recently installed Firefox 8. Immediately after installing I began to receive Java Script Application errors. When opening Firefox this message pops up "TypeError: Components.classes[componentid] is undefined". When closing, this message pops up "Reference error: M_caFxtBobj is not defined" . Also, my internet security (CA) is not working. What do I need to do? I was perfectly happy with my previous version of Firefox and this problem is not making me very happy.

Usually caused by an add-on that is either incompatible with Firefox or one that wasn't updated completely by its' developer. The former can happen when the Addon Compatibility Reporter extension is used "across the board", instead for each extension along with testing each extension.
