YouTube Autoplay Blocker

Block YouTube autoplay when opening tabs or switching back to YouTube.

Stop YouTube videos from starting automatically when you return to a previously opened tab. YouTube Autoplay Blocker is a lightweight (~18KB) extension that ensures videos remain paused when you click on an old YouTube tab. It stops the browser from auto-playing media just because the tab regained focus. The video plays only when you explicitly click Play. Why install it: - Prevents paused videos from auto-resuming when you switch back to their tab. - Gives you complete control over playback without unexpected media starts. - Fully compatible with the latest March 2026 YouTube updates. - Has zero impact on browser performance or page load times. What it blocks: - Standard YouTube videos auto-resume. - YouTube Shorts autoplay. - Miniplayer autoplay. Privacy & Cost: - 100% free with no ads. - Zero trackers and no data collection. - Code execution is strictly isolated to YouTube domains. Changelog: v1.3 (17.03.2026): - Updated core logic to match the newest YouTube DOM modifications. - Videos stay strictly paused when returning to an old tab, but play normally when you manually select a new video. Support: This extension is completely free. If you find it useful, buy me a coffee to support future updates: https://buycoffee.to/foto360
