This is a very useful add‑on.
However, when I try to right‑click an m3u8 URL to copy the link, the add‑on immediately opens and starts playing the stream instead. It would be great if this behavior could be adjusted so that right‑clicking allows copying the link normally.

Thanks for the excellent addon! With this, now I can watch IPTV within web browser without downloading any IPTV player, and I can use my Firefox bookmark to store and sync my collections of the IPTV m3u playlists instead of maintaining a .m3u playlist file.

Also, the author acts very quick for my feedback on github. I requested to make the subtitle font-size etc configurable, and the author implemented it and published the updated version within only a few days.
