Firefox - Performance

I usually use Firefox on my Mac instead of Safari simply because of the availability of A9 and the Google bar for Firefox. But Firefox's performance was really sub-par compared to its performance in Windows and Linux. I read somewhere that some people had disabled Flash from their browsers for performance reasons. I did that last night and the improvement has been an amazing. Now I can browse quite a few tabs compared to the time before I disabled Flash. Update: Maybe its Macromdia's shitty implmentation of the Flash player
