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.
