Filling up form automatically

1 of the reason i like to use FireFox is it's extendability and flexibility due to various add-ons/ plugins. Involved in signing up several accounts recently and i found the following add-on is extremely helpful for me. As simple as entering ALT-J, some of the fields are automatically filled in for me. It save me a lot of time entering words, and avoiding typo mistake as well. It help a lazy man like me, and i hope it help you too... :P Again, it's free, FOC.

Haven't get your own FIREXFOX??? Check this out!!!

I have FIREXFOX already, show me where to download Autofill Form (Open this page using FIREFOX, so that you can add the add-on right away)
