I had used Firefox on my Macs for quite a while, mainly because Firefox had tabs while Safari did not. Even once Safari got tabs, I continued using Firefox, just out of habit. Then one day, GMail refused to load in Firefox. I tried multiple times, and, while I never found out why this happened (a Firefox update? a GMail update? maybe someone here knows), I quickly ditched Firefox for Safari.
