autofill toolbar feature request

hi, i'm familiar with the current built-in autofill described in this article: https://support.mozilla.org/en-US/kb/control-firefox-automatically-fills-in-forms?esab=a&s=autofill&r=0&as=s#firefox:mac:fx29 but i would like to put in a feature request to have a toolbar button added similar to the one in Safari, where you can click the button to fill out the entire form, rather than having to click & fill each field separately as the only option. the ability to click on each field should still be kept as is though, as this is a nice feature, but with the addition of a button and form preferences where you can enter form data to be used for each field. i know there are add-ons for this (Autofill and Autofill Forms are the 2 best out of the 4 i installed and tested) but it would be great to have a built-in toolbar button.
