Yesterday i installed snow leopard and safari 4.03 is in there and it's just AMAZING , you don't wait a single second for the browser to start whereas we tal about more than a minute to launch firefox
and page loading is real fast , all i need is the old-style loading blue bar that i really liked ( why the hell did they change that ?)
Ive always liked IE ... however with the new IE 8, altho has some good features i often find it randomly crashes and does not work with xfire (IM for gaming). Because of this is started using firefox, and it seems to run alot faster and it is more secure, however it can be anoying at first as you will be required to install flash player etc... (firefox also has a bunch of addons which are useful)
I think Opera and Firefox both keep high quality ranks but i would trade FF for Opera if they implement addons i can use in my FF. However i like Safari for it`s speed.
