Simple, a little old-fashioned to configure, but works even in 2024.

This extension works for all text fields, but doesn't work in a form that contains more than one date selector (Example: buying tickets for 4 people that requires each birth dates). All the date selectors will autofill the last person's date of birth.

dose not support utf-8 languages for exporting

I mod in a chat room and this extension made my life a lot easier. Use to love it, cause it stopped working yesterday. Can't find a fix for it.

best form filler for Firefox. far more difficult than Chrome.. simple fill in of address requires tons of duplicit records.. this functionality, together with easy page translate and tab to search, is the highlight of Chrome. Wish Firefox added any productivity features, years go by...
I hate how difficult is it to reach the options of this addon.
