Was there an improvement when you disabled extensions?

I did update to the latest and still cannot get it to even open or start. to check if anything is disabled, Thanks for your help

I do not know why you ask this but I also would not know how to tell you what you ask. except the operating system XP Funnny browser worked fine last night now this morning can open it but not navigate. Type and address and nothing happens.

I think it is an internal problem at Modzilla-- maybe?

A recent update to Firefox version 45.02 has resulted in my browser becoming "non-responsive " each time I open a new tab by clicking appropriate links. This seems to be a communication breakdown between internet servers, but I have Never experienced any such problems with my ISP or earlier versions Firefox, of which I have used both for several years. I can operate one window without Firefox stalling, but every time I open any additional tabs, it becomes "non-responsive" and takes several minutes to respond properly. Too slow for my preference. As I said, older versions never had this issue. If disabling Addons is a prescribed solution, I would NOT want to use Firefox as my DEFAULT browser any longer for THAT reason. I need all Addons enabled for my normal web activity.

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

• Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
• Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
