I loved firefox until it started randomly freezing and crashing when I updated. I now stick to chrome and know that when an update to chrome comes out it won't mean I have to wait half an hour to load my email.
I'm with Firefox. I stuck with Chrome for a while but what I really like about Firefox is it's community and variety of personas and add-ons. It also functions very well for me and matches Chrome's speed.
My favourite Browser is Mozilla Firefox because it is fast, crashes are very rarely and its useful to be informed when new browser version updates are out.
