get a VPS, run Tailscale and NPM on it and switch to Jellyfin

Keep in mind that VPSs will charge for bandwidth, which adds up quickly when you’re streaming.

One suggestion I haven’t seen mentioned is contacting your ISP. Sometimes you can get a dedicated IP, although you might have to pay for it.

Alternatively you might just break down and pay for Plex Pass. I know that goes against the Lemmy philosophy to the very core, but for all its issues, Plex is still way ahead of Jellyfin in terms of features, UI/UX, etc. Jellyfin will get there, and I’m ready to switch the day that Plex becomes unusable, but that hasn’t happened yet.

This extension does a decent job.

But yeah it would be nice for Firefox to support PWAs natively.
