[Mobile] Doesn't display values

[jhonatn]

When used on mobile, it shows a template with placeholder texts, and the wrong scaling.
I don't know if it should work on mobile, but since it's almost working as of now, it would be awesome that it did.
Happened on Firefox for Android 66.0.1

Hi there! This is a use case I had not considered because I thought like Chrome extensions, Firefox add ons don't work on mobile. I will see if I can fix it. What you are seeing is the pop up when you click on the JapaneseTab icon next to the Chrome address bar.
