where a lot of things work just fine in seamonkey, i still have to use Internet Explorer for my online banking, they support several browsers:
Microsoft® Internet Explorer
version 5 and 6, and 7
or: Netscape™ Navigator™ version 7.1 and up
or :Mozilla 1.5 and up
or: AOL 8.0 and up (AOL subscribers only)
or: Firefox 1.0, 1.5 and 2.0
or: Opera 9.x
no seamonkey tho =| natwest online banking used to only be ie and firefox, so it would seem they are expanding doing something to be more compatible.

The truth is that I'm happy using both Sea Monkey and FireFox. 

FF is my primary browser and goes everywhere. However, I run a pretty restrictive (NoScript, FoxyProxy, etc) environment.

SM is smoother and works better with my bank and several other sites which I have configured to come up when I open it.

Basically, I do all of my financial stuff in SM and all other stuff in FF. If you stop and think about it, doing so increases my security because the cookies and cache for both browsers are stored in completely separate places. I never have to worry about websites visited in FF attempting to read cookies set in SM. 

On my Linux based system at home, I use Konqueror, FireFox, Sea Monkey and Opera simultaneously at times simply to maintain clean separation of web activities.

It's a security/privacy thang.

the best advantage of seamonkey is the ease of use.

When working on mail and browsing it is the easest way to do.

that's a lesson for developpers, think ease of use.

The SeaMonkey Internet Suite of apps would have been better off if the 'full' backing and support (manpower, infrastructure, money, promotion) of the Mozilla Foundation had of been behind it; however seeing that was not the case, with the Mozilla foundation moving in a different direction, the SeaMonkey Suite is much better off where it's presently at. 

And possibly could be better off still, if it had sufficient resources of its' own to further distance itself from the Mozilla Foundation; all the while maintaining and even increasing the volunteers required, essential, and invaluable input on SeaMonkey's development.

Long live the SeaMonkey all-in-one internet application suite!

Ahh yes, opinions abound. :-)

Fire vs. Water. This is just begging for a comic book-style battle.

They are probably better off without the support of the Mozilla foundation behind them. I don't know why a much larger organisation can't seem to fix the increasing number of bugs in Firefox, or why it regularly prompts you to update the software sometimes two or three days in a row. I still think the best version of Firefox was around 0.7. Version 2 is so unreliable and leaky that Mozilla should be ashamed of themselves. Fingers crossed for version 3 - the beta is promising.

I Love SEAMonkeys, You Send For Them From Ads in Comic Books, Litttle Critters Come ALL Dried UP. Man. Then ADD Water, Wait few Days & all these Live Little SEAMonkeys Swim About, Amazing. 
They Can Swim In Your Mouth ,Too. Where they live Forever.
If You Arn't So Generous with Life, SEAMonkey browser will do Streams that others refuse, especially IE, when blotched, SEAMonkey To Rescue.
If You Wonder, Seamonkey or Firefox, Come on, Where have YOU Been. Its SEAMonkey WorldWide.

Maybe this just means there isn't enough interest in the software that people aren't reporting bugs. I found the software horrible to use, and rather than continue using it, I just ditched it for other software. People only seem to submit bug reports if they actually care enough about the project to want the bug fixed.
