Return YouTube Live Subscriptions troch Tim Sherlock

Do you remember how YouTube used to group all the Live channels at the top of you subscriptions list in the sidebar so it was easy to see who was Live at any given time? I wanted that back. Return YouTube Live Subscriptions adds a “Live Subscriptions” panel to the YouTube sidebar, showing which of your subscribed channels are streaming right now.

Features:
Live sidebar panel: Always-visible list of your currently live subscriptions
Live popup tab: Quick links to live channels and their watch pages
Channel management: Scan your subscriptions, include/exclude channels from live list
Local storage: All data stays in your browser; no accounts, no API keys, no tracking
Lightweight: No ads, no bloat, just live channel status

How to Use:
Open https://www.youtube.com/feed/channels and scroll down to load all subscriptions.
Click the extension popup and go to All Subscriptions.
Click Scan from YouTube to import your subscribed channels.
Use the toggle to include/exclude channels from your live list.
Switch to the Live tab to see channels streaming right now.

How It Works:
This extension does not use the YouTube Data API. Instead, it checks each channel’s /live URL to detect if they are currently streaming, and stores your channel list locally in browser storage only.
No data is sent to external servers. Your subscription list stays on your device.

Known Limitations:
Scanning only captures channels currently visible in the https://www.youtube.com/feed/channels page. If some subscriptions dont show up, be sure to scroll all the way to the bottom, then scan again.
Live status is checked in batches to avoid overwhelming YouTube servers, so initial checks may take a few seconds for large subscription lists.

Privacy
This extension does not collect or share any data. Your subscription list is stored entirely
in your browser and never transmitted anywhere.
