I have switched to Chrome because Firefox gets stopped with scripts not working (I don't know how to fix that issue). Chrome is OK except that google talk doesn't work. I would have to use hangout which doesn't work on my computer. I run Ubuntu 14.04 on a 6 years old mini dell 9 with 1Gb ram. Firefox works fine with google talk. I'd rather use Firefox if I wouldn't have the frequent slowdowns with the scripts issue. I have ordered 2Gb of ram to see if it improves the running of the computer.

I hope this is what you talked about...
