🎬 EasyTube V4 — All-in-One YouTube Enhancement

Skip ads instantly. Block sponsors. Force 4K. Download via Cobalt.
One floating panel. Zero bloat. Settings remembered. Works right now.

✨ Features

🖥 How It Works

EasyTube adds a small floating YouTube-logo toggle button to the bottom-right of every YouTube page.
Click it to open the control panel, where you can individually toggle each feature ON/OFF:

• Ad Skip — enable/disable ad skipping (MutationObserver + 16x speed + seek)
• SponsorBlock — enable/disable sponsor segment skipping/muting
• Auto 4K — enable/disable quality forcing

The panel also shows the current video title, video ID, and a Download HD button.
All toggle states are saved automatically — no need to re-enable on every visit.

⚙️ Technical Details

V3 Ad Skip (new method)

• MutationObserver on #movie_player detects ad injection instantly (< 1ms reaction vs 500ms interval in V2)
• 16x playbackRate trick for unskippable ads — video speeds through the ad in ~1–2 seconds instead of waiting it out
• Synthetic MouseEvent dispatch to bypass YouTube's isTrusted click checks
• 400ms fallback interval catches any edge cases the Observer might miss
• 5 enforcement popup selectors for maximum adblock bypass coverage

SponsorBlock

• Uses the SponsorBlock public API (CC BY-NC-SA 4.0)
• SHA-256 hash-prefix privacy endpoint — your exact videoID is never sent to the server
• Supports both skip (seek over) and mute actionTypes

Quality

• Hooks into YouTube's native movie_player API (getAvailableQualityLevels, setPlaybackQuality)
• Retries at 1.5s / 3s / 5s after navigation for reliable quality lock

Download — Cobalt API (V3 upgrade)

• POST request to Cobalt public instances with videoQuality: "max"
• Tries 3 instances in order: co.wuk.sh → cobalt.api.timelessnesses.me → api.cobalt.tools
• Falls back to redirect service if all Cobalt instances fail
• No ads, no tracking, no paywalls — direct download link

SPA Navigation

• MutationObserver + yt-navigate-finish + yt-page-data-updated events keep everything in sync across YouTube's single-page navigation

📦 Compatibility

🔒 Privacy

• No data collection. EasyTube never sends any user data anywhere.
• SponsorBlock requests use SHA-256 hash prefix — only the first 4 hex chars of the video ID hash are sent. The server cannot reconstruct which video you're watching.
• No external analytics, no telemetry, no tracking scripts.
• Settings are stored locally via GM_setValue — never leaves your browser.
