Yeah, recently i installed new firefox 3 in my notebook and Must tell it here because of some interesting about this firefox 3 to be had.
The reason I download firefox 3 is caused latest software is commonly has better performance, not except Mozilla firefox. Another reason is caused my firefox 2 frequently crash and slow turtle, I don’t think what is the problem, may be my old notebook has no eanough memory RAM I think.
And then finally I install firefox 3 to change my firefox 2. The result is very glading. The new display of navigation toolbar of firefox 3 gives me new nice condition of look browser. And this is felt more faster performa than before, but some my add on that installed on firefox 2 does not supported in firefox 3, such as real player video detector and AVG link scan that usually checking pishing link for me.
But nevermind, firefox 3 gives me good look, may be you must to try it on your computer too.
