Ok, here's something dang cool.  If you don't mind doing a bit of
editing, this file, when you drop it in your /usr/local/bin you'll be
able to tell firefox to launch the site in a new tab/window if firefox
is already running.  I personally love this feature.  The script is
attached at the end after being cleaned up a bit.

It should be fairly straight foward, just change the two varibles. (the
part in quotes that says "tab" and "/usr/lib/MozillaFirefox" to the
correct things).

Enjoy!
