I use that addon currently on my firefox, its compatible with the android version, but to install it you must create a addon collection with that extension in it and add it to your brwser, detailed instruction are available online. Or you could try Iceraven which is a fork of android firefox, it has this extension in its collection.
The comment by user unverifiedApk down in this thread has instruction on using custom collection if you decide to go down path.
Thanks for the tip, I'll have a look!
