Welcome SeaMonkey 2.0!
Why?
Here are some reasons why SeaMonkey is better than Firefox:
1) Uses only 56MB on google.com, while Firefox uses 86MB
2) Faster than Firefox 3.5.5. Firefox 2.0 was always faster, and SeaMonkey is based on that.
3) Firefox 3 introduced frequent crashing, especially when you close and reopen it quickly, but also randomly when you open it.
4) SeaMonkey has also e-mail, graphical HTML editor, and IRC built-in. Still it uses less memory than Firefox.
5) Firefox takes sometimes 10-20 seconds to open certain Ajax based chats on forums.
6) SeaMonkey runs also on Windows, Mac, Linux (just like Firefox).
7) It has less security holes, and is less attacked (since most attackers focus on IE and Firefox).
8) Firefox takes over 30 seconds on first time to open when I start my PC.
9) It has collapsible toolbars, and sidebars, just like Notes 8!
10) It has profile switching! This is very useful for web developers, as they don't need to use different browsers for each user, or close all browser windows to switch a user.
11) It has probably a lot more benefits over Firefox, but I just started using it an hour ago :)
