It's not like Mozilla is removing features from SeaMonkey when they create Firefox. Firefox is the primary application from Mozilla. SeaMonkey is a 3rd party project derived from Firefox code, and the SeaMonkey project adds features that aren't included in Firefox.

There are a number of extensions that add "Form Fill" features to Firefox, and there is at least one extension that adds "form history management" to Firefox.
