Interestingly not supported on Firefox Android. It's the first time I come across an add-on that doesn't work on both.
Firefox on Android only supports a handful of curated add-ons. You can apparently create your own collections or install anything with Firefox Nightly but I've not done this.
You can do that with Firefox Beta too, which likely will give you better experience / stability. It's a shame you have to jump through so many hoops to get it working.
