Ever since the last update of the firefox browser the browser takes too long to open and also it hangs a lot and then crashes and when it starts again it either is unable to open to the pages it has crashed at or just does not restart. I am having to turn off computer to restart the browser and that too at times does not start I have to bomb out thru task manager and restart. I have now tried re installing Firefox twice but to no effect. Before I switch over to another browser I would request your assistance.
