Mor автор Overhypedcat

Mor is a Firefox extension for Twitch with two features:

Music filter: remove songs from Twitch streams

Mor recognizes the song a streamer is playing (Shazam), fetches its clean copy from YouTube Music or YouTube, finds exactly where in the song the stream is, and subtracts the song from the stream's sound as it plays, matching the streamer's volume and EQ. The streamer's voice, the game and alerts stay. It's on for every channel from the start; switch it off per channel from Mor's toolbar button. What it's doing shows in Twitch's player controls.

1440p unlock: watch region-locked 1440p Twitch streams

Twitch offers its 1440p (Enhanced Broadcasting) copies only in some countries. Mor asks Twitch for the stream through a WireGuard VPN server you add (a free Proton VPN server works) and plays it in Twitch's own player, with 1440p available in its quality menu. Only that tab's Twitch video goes through the VPN, and only while you watch.

Mor needs its helper.

The work is done by a small helper program on your PC (Windows 10 and 11), which Firefox starts only while Mor needs it. It has no window and stops when you leave Twitch or close Firefox. Install it once: download Mor from https://github.com/Overhypedcat/Mor/releases/latest (Source code zip), unzip it, and double-click Install Mor.cmd. Mor's toolbar button shows these steps when the helper is missing.

Heads-up

• Some songs won't be removed: niche songs Shazam doesn't know, or versions YouTube doesn't have (remixes, sped-up or live versions). Mor says so when it happens.
• Loud music can leave faint traces, since Twitch re-encodes each stream's sound.
• Your antivirus may flag the helper as unknown the first time (a false positive): it's built on your PC when you install it. The full source is on GitHub.

Privacy:

Nothing about you is collected. Short clips of the stream's sound go to Shazam to name songs; songs are searched and downloaded from YouTube; everything else (your VPN files, your Twitch login, song copies) stays on your PC. No account, no analytics, no telemetry.

Works alongside Twitch ad blockers and 7TV.
