NicholasBly/youtube-webos 0.8.2 on GitHub

[0.8.2] - 2026/08/12

Check current visibility of controls before sending back button - #159
Fixed player state events relying on the Force Max Quality setting (clock and SponsorBlock overlay missed visibility updates)
Fixed seek-burst notifications not updating their text when the same message was already on screen
Optimized some files not using shared helpers, enabling less resource/object usage
Twemoji 16.0.1 is used for emoji fix on webOS 3/4, but version 17.0.2 is imported in package.json. Matched both to 16.0.1

Fixed manual skip segments causing notification buildup - #151
Additional fixes to the skip logic — #141
- Race condition: a same-position or backwards seek could leave isSkipping stuck true until manually seeking again.
- Race condition: the yt-player-state-change "playing" event could fire while video.paused was still true, so the timeupdate listener would fail to re-attach and segments would stop getting skipped for the rest of the video
Fixed sponsorblock colored overlays sometimes disappearing and not reattaching after exiting a sponsorblock segment
Fixed SponsorBlock colored segment overlay not functioning properly if the video was restarted from the endscreen

Fixed a typo in ui.js - window.sponsorblock?.buildOverlay() -> window.sponsorblock?.drawOverlay()
UI.js, SponsorBlock-UI.js: Load icons locally

Converted RESPONSE_NEEDLE_RE to a simple data.x check as it eliminates a regex scan when the data is already parsed at this point
Fixed some listener removals

handleLaunch uses a string prefix match for the YouTube URL, which is unsafe, as https://www.youtube.com.attacker.example/x can pass this check

(Debugging) Moved console log for "Resolving" to debug flag, preventing pile up of console logs
Consolidated all small polyfills into polyfills.js - previously some overlap between userScript.js, utils.js, ui.js, and SponsorBlock.js.
Removed ~350 lines of dead and duplicated code. Shared helpers for element lookups, caching and polyfills now live in one place instead of being reimplemented per file

Moved sponsorblock colored segment overlays to a sibling of the progress bar, preventing the app from constantly removing the css rules and redrawing

Use a breadth-first search with max depth of 6
Remove deep cloning (structuredClone) in favor of Boolean mutation (NoAd false to true)
Remove fallback clone method which can corrupt non-serializable data. New version operates on the original object itself, so it doesn't require a clone

Reduced MutationObserver coverage. Replaced the single attributes + subtree: true observer with two narrower observers: a childList-only subtree observer (detects the progress bar being destroyed/recreated) and an attribute observer pinned directly to the tracked bar element. Eliminates per-animation-frame mutation callbacks caused by YouTube's own style writes on playhead/buffer descendants.
Eliminated redundant reflows in overlay positioning (_syncOverlayPosition) when nothing changed.
Build segment description strings (toFixed) only when a skipchain is identified instead of anticipating the next skip to be a chainskip (also on every seeked event).
SponsorBlock binds to the video as soon as it appears instead of polling for it, so segments are ready sooner
Compile constant arrays for 'categories' and 'actionTypes' once globally instead of on every video load
Convert div.style.backgroundColor, div.style.width, div.style.top to div.style.cssText
executeChainSkip: break loop whenever we find the next segment past the current time instead of looping through the entire array

Return Dislike no longer polls in the background for the entire video. It now checks for ~10 seconds after load and when you interact with the panel, then goes idle - noticeably less CPU during playback on older TVs

Fixed a slow memory leak in the Shorts screensaver keep-alive that grew for as long as Shorts stayed open

Shortcut buttons respond faster - a redundant full-page element search was running on every keypress
Refactor play/pause logic to eliminate unnecessary code execution
Event hander: move input/text area fast-fail check towards the top of the function to eliminate unnecessary code from running
Skip Chapter: Eliminate double looping of chapter calculation
Toggle comments: Replace || operator with a comma to do one query selector DOM pass instead of two
Eliminate redundant traversals in green button menu logic

Testing fix for #157 where memory on older TVs is very scarce
Added buffer-limit.js to src/hooks
Caps video buffer playback to 30 seconds on webOS 3 and webOS 4 by trimming playback range behind playhead
Omitted buffer-limit.js from modern build
