I’ve had it with Firefox 3. It’s slow, crashy, a resource hog and did I mention it’s slow? Not quite IE 7 slow, but not nearly as fast as I wish it was. Yes, it could be add-ins slowing it down, but I really don’t run that many as you’ll see below. I don’t even use Greasemonkey.
At least until Firefox 3.5 (which I know is as soon as next week) or a release version of Chrome for Mac comes along, I am trying to run with Safari 4 as my default browser. It’s tons faster, especially for heavy sites I live in like Salesforce and Fever. And while it can be as much of a resource hog as Firefox, it takes a lot longer to get to the must-quit-and-restart-this-beast point than Firefox does.
