I think FF3 is the fastest browser among the most popular browsers. Opera, Chrome and Safari among the others.
Of course Firefox! I’m always using around 50-100 tabs which saves when I close browser and it works great! It’s like desktop icons that takes much space, but I just can’t delete them
I use FF all the time, fastest of all… Fast in searching bugs, codes, HTML structure, image capturing, add ons and more.
