This is best answer in this entire thread.
Personally, I seldom use use Safari, and greatly prefer Firefox with several select add-ons. If you're running Snow Leopard in 64 bit mode, that's the only time you might see a noticeable difference between the 2 browsers.
Also, for the sake of not offending those who believe they know different, and become rude, let's say that I'm only stating opinion.
A lot of "Don't use X" being thrown around.
But I still have the same questions, Which Mac ? Which OS ?
A lot whine about the Firefox add-ons slowng the browser down, and constantly nagging for updates. This is only if you set the Firefox preferences to automatically check for updates. And if you load up dozens of add-ons, that you usually don't need. Firefox is never slow on a Mac Pro.
Like I tried to explain in my last post, Safari is fast and mostly reliable. But, if you need the use of add-ons, Firefox blows Safari out of the water. Knowing the OP's Mac and OS would help with a more definite answer.
