YouTube Tweak - YouTube強化拡張機能、快適な視聴体験を実現 作成者: honglinus

YouTube Tweak is great — YT Enhance Pro keeps the same spirit: a privacy-first, fully local extension that fixes YouTube's annoyances and adds the customizations you wish the official site had.

• Lock video quality — auto-switch every video to your preferred resolution (144p up to 8K, with automatic fallback when a video doesn't offer it).
• Speed buttons & slider — 0.5x / 1x / 1.5x / 2x one-click presets plus a fine-grained slider, and optional mouse-wheel speed control.
• Remember playback speed — keep your speed setting across videos.
• Volume booster — real gain beyond 100%, and a "true 100%" option for the max volume.
• Video zoom — zoom into the video with the mouse wheel.
• Rotate / mirror / screenshot buttons in the player.
• Scrolling mini player — the video keeps floating while you scroll.
• Remember subtitle state per video, and cleaner UI (translucent end screen, progress bar below the video, corner time display).

• Translate video titles, descriptions, summaries, subtitles and comments into your target language — automatic or on demand.
• Line-by-line comment translation and a manual translate button for comments you choose.
• "Never translate" language list to keep specific languages untouched.

• Lock the number of video rows on the home page.
• Show commenter nicknames and auto-expand long comments.

• Block image/text ads and creator product placements.
• Block Shorts in the home feed, search results, watch page and sidebar.
• Disguise the premium logo and remove the country code label from the logo.
• Custom CSS injection for power users.

• Every feature can be toggled on or off.
• Export / import / reset your configuration anytime.
• No trackers, no analytics, no data collection. All settings are stored locally in your browser. Nothing is sent anywhere.
• Based on the open-source project YouTubeTweak (MIT License).

• storage — saves your settings locally in the browser.
• tabs — detects the current YouTube tab so the popup can reflect its state.
• Host permission *://*.youtube.com/* — the extension only touches YouTube pages and nothing else.
