Doesn't work at all in the latest Firefox Beta for Android. Or Firefox for Android in general.
A shame, because it's flawless if executed in a desktop PC.

The Development had the good foresight to listen to Mozilla and update their add-on, before the final release of Firefox 57. As a result, it is completely compatible.

read their "privacy" policy and antiquated ToS before installing

Set privacy.resistFingerprinting to false and the addon work again or use the dev version 4.5.5564beta, the issue is fixed. :)
