As you may know, I like trying out different browsers. I have been using the new SeaMonkey 2.0.3 browser and am really beginning to enjoy this old school browser.
Like Firefox, SeaMonkey supports the FlashBlock add-on which goes a long way to avoiding those poorly written, CPU hogging, Flash ads. It has a new default theme that is clean and easy on the eyes. SeaMonkey also has the ability to show favicons for bookmarks on the toolbar. Plus since it uses the same rendering engine as Firefox, its fast and compatible with most websites. The only feature it currently is missing is the ability to double click and open a tab on the tab bar.
I use it a lot for the multiple profile feature which allows me to run as different users in the same browser. Firefox has can do this, but the feature is more up front and easier to use in SeaMonkey.
Check it out if you want to try an old school browser. And don't forget the integrated e-mail, IRC chat client, and page editor (Composer) that are integrated into this browser.
