✨ Features

Feature | Details
🚫 Ad Skipper | Instantly skips all ad types — skippable, unskippable (16x speed trick), banners, overlays. MutationObserver-based for zero-delay detection
⏭ SponsorBlock | Skips or mutes 9 segment types: sponsor, selfpromo, interaction, intro, outro, preview, music_offtopic, filler, exclusive_access
🎥 Auto HD Quality | Forces highest available quality (8K → 4K → 1440p → 1080p) on every video load, with 3 automatic retries
⬇ HD Downloader | One-click download powered by Cobalt API (3 public instances with automatic fallback)
🛡 Adblock Bypass | Automatically dismisses YouTube's adblock enforcement popup using multiple selector strategies
💾 Persistent Settings | Remembers your ON/OFF toggles across page reloads and sessions
📊 Stats Panel | Floating draggable panel — live ad skip count, sponsor count, video info

🖥 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

Manager | Status
Tampermonkey (Chrome / Firefox / Edge) | ✅ Fully tested
Violentmonkey (Chrome / Firefox) | ✅ Fully tested
Greasemonkey (Firefox) | ⚠️ Not tested

🔒 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.
