I have been having a frustrating problem where my Firefox suddenly becomes unresponsive, for which the only solution is launch Task Manager and killing the Firefox process. After having my RAM doubled, it was still happening. I had an epiphany and wondered whether my recent discovery and installation of Autohotkey was the problem, so I deactivated Autohotkey and Firefox is now behaving.
But I love Autohotkey!
It makes my life SO much easier, and I don't want to permanently get rid of it! 
So if anyone can give advice or help to resolve the personality issues Autohotkey has with Google-searching in Firefox, that would be fantastic!Thank you to the contributors.
