Ela funciona muito bem em desktop e no celular.

For Android it can be improved. I've been using it for Chrome+Mac combination and has been wonderful. Horrible experience when using Android+Firefox combination, it just doesn't autofill nothing, you need to explicitely give Accessibility access which is not explained anywhere.

The Best of the Best!

Bitwarden support reports that this add-on is not officially supported and that web page autofill with Firefox Android should be accomplished using the Bitwarden Android app.
