Removing “SeaMonkey” from window title bar
Let’s continue our polishing of SeaMonkey, the best browser the Windows platform has ever seen.
Intro
When installed the SeaMonkey browser, like many others, shows the word SeaMonkey on each browser window. This may be a good practice for some apps, but for a browser, where the title bar can be quite useful and very often read, it just means you’ll be xeroxing that word onto your brain day after day.
Also, instead of using Gmail notifiers and other memory baggage to inform you of new email, you might just keep a minimised browser window in your taskbar and watch out when the message count changes.
How to remove the word “SeaMonkey” from the browser window
Now let’s get down to business and remove that last unnecessary piece of UI in this nice and fast little app.
First navigate to the directory “C:\Program Files\mozilla.org\SeaMonkey\chrome” and find the file en-US.jar. This is a .jar file and its structure is virtually that of a .zip file, so go ahead an open it in 7-zip or similar. (If you’re having trouble opening the .jar file with your ZIP file manager, you can rename it to .zip, go through the procedure below, then back to .jar when finished).

Once inside the “en-US.jar” go down the directory structure to “\locale\en-US\navigator\” where you’ll find navigator.dtd. This is your file. If you’re using 7-zip (recommended) and a reasonable editor (like jEdit or PSPad) just hit F4 and edit this file.

Just remove “&brandShortName;” twice, then remove the dash below in the line marked “…separator”, save and you’re done.
That’s it. You can now restart your browser and enjoy.

Screenshot above shows the title bar showing gmail and the number of unread messages without the additional and unhelpful ” - SeaMonkey” text.
