Can't believe I've been using Firefox on Android for 2 years and only just discovered this add-on. It should be a standard feature in the options, Firefox! Thanks very much to the developer.

=)

Thank you for this, it just works fine.

Thank you, thank you, thank you! The lack of this addon for 57+ was one of the things keeping me on an older version. Keep up the good work.

Thank you. I waited for that.

Just works. Finally.
