I tried it and it does seem to be somewhat faster,

But I have had problems with Realplayer 11 doing video downloads with Firefox and Safari even though it worked in Internet Explorer. Resizing the window in Safari can only be done from the lower right corner. I find that really annoying. To move the top of the window down without the bottom going off the screen you must go to the lower right corner to shrink it then got back to the top to move it down.

At present I mostly use Firefox but if something doesn't work there I test it with Internet Explorer. I haven't found where Safari has sufficient advantage to justify the irritations.

um
