A good form filler?

[pro2a]

I'm looking for some type of form filler that I can enter all my master information in to and save it. When ever I need to enter info on a website, just click a button and have it auto populate instead of typing it all in. I've seen them, but can never seem to find a good or legit one. Any ideas? Thanks.

I know Firefox had several add-ons that did this; can't remember any of the names of them, but I know it had them.

LastPass is the one I use.

I gave last pass a try, I like it so far.
