Greetings!

I'm looking for a way to write a VB program that will:

1) Open FireFox (Or any other Web Browser)
2) Go to a site
3) fill-in my login and password (so I won't have to anymore ;P)

I realize I can just install some macros from the FireFox add-on site, but hey that's boring o:

Do note that I'm just a beginner, and have very feeble knowledge of VB.
Any help would be nice <:
