I prefer using a form-filling add-on because it has better control.

Go to the Mozilla Add-ons Web Page {web Link} (There’s a lot of good stuff here) and search for what you want.

I have already searched through the Mozilla firefox addons page. I cannot find a single addon that uses the already saved autofill, they use their own data that is stored through their item (e.g. name, address, phone number).

I would like to add, the information I am filling into the boxes do not include names, addresses, and phone numbers. They are not always the same data too, but a extension that can autofill any data that is already saved would save alot of time and hand gestures (this way I only need to insert data that has not already been inserted before).
