Has this addon been scrubbed off the internet? - Add-on Support - Mozilla Discourse

On my desktop here i have this “ blocker” you see the icon? i cannot for the life of me find it when searching on my steam deck firefox. has it been removed from the addon website, i couldn’t find it on git either. or maybe i did but i wasn’t allowed to install an untrusted addon or whatever firefox said, this provided i even found the correct xpi on git, (or was it github?).
