Thanks! What's missing to get this extension to five-stars?

It doesn't work on mobile because Firefox on mobile doesn't (yet) allow extensions to do the same things they can on Desktop. There is nothing I can do about it unfortunately, which is why I did not mark this extension as compatible with mobile. We have to wait. It is unfortunate you chose to lower your rating based on something that is out of my control and which I never claimed the extension is capable of doing.
