Today, 3 March 2025, two similar extensions failed me on Firefox 135.0.1. (This type of extension has a tendency to break once in a while, requiring reinstallation.) This extension is working and is available for Firefox on Android too. So, I'm going settle for this one for a while.

it works on Android which is all I ask for. It is a bit tricky to use, but that is probably due to android Firefox limitations anyways, so props to the devs

Tried a different copy link text extension which didn't work, much to my chagrin. This one does work for me, cheers! Running Firefox 115 ESR on macOS 10.13.

This Extension actually works on mobile, thanks

Finally an extension that works on mobile 😭, thank you so much ❤️
