How can I get FireFox to automatically fill in an entire form?

Solution 1:

You could try the Autofill forms add-on.

Solution 2:

There are many password manager add-ons that can assist with this. I personally use LastPass. You could also try Roboform. Both of these work great! Their form filling capabilities work quite well.

Solution 3:

Here are some addons I've tried - I wound up using FireForm as it seemed to work well - just click on a toolbar button to fill in a form. Autofill Forms was similar but it seems to have some problems with the UI.
