Nowly by Gaëtan H

Nowly shows your Firefox activity on Discord: YouTube, Netflix, Twitch, Disney+, and other supported sites.

How it works
- Install this add-on, then install Nowly Host (free desktop app): https://nowly.me/host
- Keep the Discord desktop app running on the same computer
- Open a supported site and play something — your Discord Rich Presence updates automatically

Features
- Presence library inside the sidebar (install only the sites you use)
- Per-site settings for what appears on Discord
- Pause or resume presence with a keyboard shortcut
- Optional analytics, off by default

Nowly Host and Discord desktop are required. The add-on alone cannot talk to Discord. Nowly is not affiliated with Discord.
