More than tabs автор Felipe Ramos

What it does
More than tabs keeps your browser tidy by ensuring only one YouTube tab can exist at a time.
As soon as you open (or switch) to another youtube.com page, the extension:
Closes the newest YouTube tab
Focuses the oldest remaining YouTube tab

Key features
One‑click toggle – enable/disable directly in the popup
Instant enforcement – when you switch it on, it trims excess YouTube tabs right away
Ultra‑lightweight – <10 KB, runs entirely locally, no remote requests
Privacy‑friendly – needs only the “tabs” permission; never reads page content, logs or phones home
Open‑source – code available on GitHub for transparency and contributions

How to use
Install the add‑on
Click the icon in the toolbar
Press the round power button to activate
Enjoy a single distraction‑free YouTube tab; toggle off anytime

Permissions explained
Permission Why it’s needed
