About YouTube Spoiler Blocker

Tired of YouTube thumbnails, hover previews, and titles giving away what happens before you even press play? YouTube Spoiler Blocker blurs every video's thumbnail, stops the hover-preview from playing, and hides the hover tooltip that leaks the full title — so nothing is spoiled before you watch. Click a thumbnail to open the video as usual. Great for sports highlights: it hides the score in the title while keeping the two team names readable, so you still know which match it is. Click the title to reveal the hidden part when you're ready. Features • Blurs every video thumbnail (where scores/spoilers often show) • Stops the hover-preview from playing • Hides the hover tooltip that leaks the full title • For sports: hides the score in titles, keeps team names visible • Click a title to reveal the hidden score/description • One On/Off toggle — nothing else to configure No account, no tracking, no data collection. Works entirely in your browser.
