Sometimes there were problems with plugins in Chrome and Firefox. In my opinion both of them are good for work. Probably Chrome is better optimized and need less resources.
I think Google Chrome is more user-friendly, fast, handy and modern-looking, nevertheless, I prefer Mozilla Firefox even if I reluctantly accept that Google's Chrome is better. Somehow, with its unique add-ons, Mozilla's Firefox has some competitive powers too.
Firefox is the best browser compare with other and it's best browser for me and Google is the main things to give the All Solution to Some time person didn't know..
