Auto Form Fill Program

[gaming_mouse]

Since I fill out so many forms signing up for poker sites and casino sites, I wonder if there is a program that could help speed this up. I know IE and Firefox have the built in helper, but I'm imagining something different:

A program that would allow me to right-click on any form field, and then bring up a menu with my commonly used form entries: first name, last name, etc. I would select that entry from the popup menu, and the program would fill it in.

Does anyone know of something like this? Perhaps a Firefox extension?

thanks for any ideas,
gm
