Yea, it sorta works, nothing to write home about though.
I first noticed it when I decided to try google chrome, and I gotta say that they have the feature perfected.
When i found this for mozilla, i was exited, but soon let down at the results.
While you get some autofill, it is in no way as functional as it’s chrome rival.
HOpe there’s an addon or something for this somewhere
