The Mozilla project says that as of today, Firefox — in all its versions and platforms — has been downloaded a billion times. That’s pretty impressive.
I use Firefox for the Mac (current version 3.5.1) almost exclusively, though Apple’s Safari serves when I want to have a second, independent, browser running.
Every so often (generally after a major update) I try to switch to Safari as my default browser, but then always switch back to Firefox after a couple of days. I know that Apple claims that Safari is faster, but Firefox is better.
What about Google’s Chrome? I’d love to try it, but Google still hasn’t released a version for Mac OS X. In June, Google offered a Mac alpha of the open-source version, called Chromium. You can download the Chromium alphas for Mac and Linux, but Google recommends:
DON’T DOWNLOAD THEM! Unless of course you are a developer or take great pleasure in incomplete, unpredictable, and potentially crashing software.
Even though I’m a developer, I’ll wait, thanks.
