YouTube Cinema Mode Plus

Hide everything except the video player in YouTube cinema/theater mode for a distraction-free experience

YouTube Cinema Mode Plus transforms YouTube's built-in cinema/theater mode into a true distraction-free viewing experience. When you activate theater mode (press 't' or click the theater button), this extension: • Hides the top navigation bar • Hides comments, related videos, and sidebar • Hides video description and metadata • Makes the video player fill your entire viewport • Removes scrollbars to eliminate white-space gaps When you exit theater mode, everything returns to normal — no settings to configure, no buttons to click. Perfect for: • Watching tutorials and coding videos without distractions • Conference talks and presentations • Focused viewing of any content The extension is lightweight (pure CSS, no background processes), open source, and collects zero data.
