Today I started using FireFox because of this issue, and I like it very much. It's fast and does about everything I want it to. Oh, and I LOVE tabbed browsing!!
There's only one thing I miss : with IE, my bookmarks were always visible in a separate column at the left hand side of my browser screen, which made surfing really easy. WIth FireFox I always have to click on bookmarks and scroll to where the correct link is. This annoys me. Is there a way to always make my bookmarks visible with FireFox too?
