How do I actually activate/install it? It does not appear in my add ons
Try this. You can add any add-on to Firefox on Android by using your own custom add-on collection. It works great!
Yes but this is a theme, not an extension (like Dark Reader is). Can you add themes to your custom add-on collection?
Since this community is for Android
I assume you want AMOLED dark in Firefox Android
Sadly you cannot apply add-on themes on Firefox Android
Although you can use add-on like dark reader to make website AMOLED dark
Maybe look in themes section, located bottom left addons page in Firefox desktop.
On Android, it doesn’t appear to be possible yet - https://connect.mozilla.org/t5/ideas/provide-a-black-dark-mode-in-firefox-mobile/idi-p/2578/page/2#comments
