About this extension
YT Channels is not affiliated with, sponsored by or endorsed by YouTube or Google.
Sort the YouTube channels you watch into your own categories, then open one at a time and see just its newest videos. No algorithm, no Shorts, no giant undifferentiated feed.
Worth knowing: YouTube's feeds carry only a channel's 15 most recent uploads, and live streams and premieres do not appear for channels that also post regular uploads.
Requires Firefox 140 or newer. Source and bug reports: github.com/Project0B/YT-Channels — GPL-3.0.
Sort the YouTube channels you watch into your own categories, then open one at a time and see just its newest videos. No algorithm, no Shorts, no giant undifferentiated feed.
- Your categories. Name them anything; a channel can sit in several, or in none. Add one by pasting a YouTube link or handle — no API key, no account.
- One category at a time. The feed page opens with your categories as tabs and a video grid below. Videos load only for the category you open, and are cached, so switching back is instant.
- Watch progress. A bar on each card shows how far you got, recorded while you watch on youtube.com in this browser. A corner button marks a video watched.
- Fully local. Categories, channels and progress stay in Firefox's storage. No account, no sync, no telemetry — the add-on contacts only youtube.com and its image servers. Privacy policy

• YouTube's RSS feeds cap at the 15 most recent uploads per channel. A channel that posts more than 15 times between visits will show gaps rather than a full history. This is a hard limit of the feed source, not something the extension can work around without an API key.
• Firefox for Android and Chrome/Edge are not supported or tested.
• No cloud sync, or automatic background notifications in this version.
