Every time I update over the last 2 yrs approx. The browser gets slower as it has so much funtionality. My PC is taking too long to start up Firefox and I have done as much as poss. using your troubleshooting. Also used PC improvement SW, plus what I know as former PC support tech. person, to improve things. IBM's keylogging SW called trustee is not keeping up with you, so again making problems. Especially online banking. I'm pissed off with this and actively looking at alternative browsers.
