Is Native MPEG-Dash + HLS Playback safe?

Clean risk

This extension plays HLS and MPEG-DASH links directly in Firefox instead of downloading them.

When you click an .m3u8 or .mpd link, the extension checks the link and opens a new tab with a video player. The player uses hls.js and dash.js to handle HLS and MPEG-DASH playback in the browser. Its permissions allow it to work across websites, manage tabs, use storage, add context menu items, and apply declarative network request rules.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
