[6.4.8] - 2026-04-24

Fixed
Native Recovery Probe Stability - Now requires two clean native recovery probes before ending an ad cycle, reducing false post-ad reloads when Twitch briefly serves a clean playlist before returning ad markers.

Pre-Roll Handoff Stability - Pre-roll recovery now keeps the same ad cycle alive longer during Twitch's native-player handoff, reducing duplicate Ad ended/reload phases.

hotfix

[6.4.4] - 2026-04-17

Fixed
Backup Hold Recovery - Continues serving and refreshing the last known clean backup playlist while native recovery is still ad-marked, preventing immediate re-entry into ad cycles after an ad window.

Forced Native Reload Removal - Removed the timed ad-end reload fallback that could reload the player into Twitch’s ad path before native recovery was fully clean.

[6.3.9] - 2026-04-17

Fixed
Post-Ad Player Reload - Restored post-ad recovery so once ad blocking finishes, the Twitch player reloads with a fresh access token and a new media player instance.

Removed Backup Hold Regression - Reverted the backup-hold behavior from v6.3.8 so recovery now reloads the native player instead of staying pinned to the backup stream.

[6.3.8] - 2026-04-17

Fixed
Backup Hold Fix - When native recovery is still ad-marked after an ad break, the extension now keeps serving and refreshing the backup stream instead of forcing a reload back into Twitch’s ad path.

Ad-End Wait Stability - The worker now keeps the active ad cycle alive until native recovery is actually clean, reducing post-ad stalls and worker crashes during longer midroll ad windows.

[6.3.7] - 2026-04-17

Fixed
Post-Ad Restart Loop - Restored ad-end stabilization so an ad cycle now ends only after multiple clean playlists and a native recovery check, preventing false exits caused by transient clean playlists during ad transitions.

Backup Stream Exit Re-Entry - Backup and fallback stream exits no longer force immediate native reloads or pause/play pulses unless truly needed, reducing cases where recovery re-enters Twitch’s ad-marked path right after ads end.

Continuation Detection - Same-context ad detections after a guarded recovery reload are now treated as continuations of the current ad cycle instead of triggering a new blocked-ad event.

[6.3.6] - 2026-04-15

Fixed
Twitch Channel Switching Bug - Fixed a critical issue where switching between channels in Twitch’s SPA could cause the ad blocker to use a backup stream from the previous channel. Added stronger SPA navigation handling and improved stale state cleanup so playback context now stays correctly synchronized during channel changes.

Stream Selection Fallback Leaks - Tightened fallback stream selection logic to prevent cross-channel stream leaks when URL matching fails, ensuring ad recovery only uses streams from the currently active channel.

[6.3.5] - 2026-04-14

Fixed
Ad-Recovery Infinite Preroll Loop - Fixed an issue where ad recovery could get stuck in a never-ending preroll loop, rapidly switching between backup streams and reloading the player. Ad endings now require multiple consecutive clean playlists before recovery exits, reducing false exits caused by temporary empty .m3u8 responses. Native token rewriting is also now disabled by default to prevent immediate preroll retriggers after recovery.

Fetch Response Property Synchronization - Fabricated Response objects created inside the worker bridge now preserve native url, ok, redirected, and type properties, fixing compatibility issues that caused Amazon IVS WASM playback failures and internal network errors.

[6.3.4] - 2026-04-14

Fixed
Worker Crash Recovery - Fixed an issue where a single IVS WASM worker crash could emit multiple error events and prematurely exhaust all restart attempts. Each worker crash is now counted only once, ensuring restart recovery can proceed correctly and playback has a chance to recover.

[6.3.3] - 2026-04-14

Fixed
Ad Flash After Ad Break - Preserved backup stream caches across ad-end resets so if Twitch briefly re-enters ad mode after a reload, recovery can immediately reuse known-good backup streams instead of re-probing from scratch, preventing multi-second ad flashes.

Simplified Ad-End Recovery - Removed the slow native recovery verification step that waited on extra token and playlist checks before ending an ad break. Ad recovery now ends immediately on the first clean playlist, making returns to normal playback much faster.

Removed
Grace Window Suppression - Removed the temporary ad-end grace suppression logic, since preserved backup caches now allow seamless re-entry handling without needing extra suppression delays.

[6.3.1] - 2026-04-13

Fixed
Critical Worker Fix - Fixed a worker crash where missing resolution helper functions caused ad processing to fail silently, allowing full ads to play through unblocked.

[6.3.0] - 2026-04-13

Fixed
V2 API Ad Blocking - Fixed Twitch v2 API variant URL handling so raw CDN variant URLs are now recognized correctly, restoring reliable mid-roll ad blocking on streams using the newer API format.

Stream Info Lookup Fallback - Added stronger fallback matching when variant URL lookup fails, reducing cases where ad-marked playlists could slip through due to CDN format changes.

Ad Flash from Prefetch Hints - All Twitch prefetch hints are now stripped during ads, preventing uncached ad segment preloads that could briefly flash ad content before blocking takes over.

Empty Segment MP4 - Replaced the minimal empty segment with a fully valid fragmented MP4 structure, preventing decoder crashes and playback instability.

Worker Stability - Fixed worker crashes caused by invalid decoder input during channel navigation and prevented infinite worker restart loops.

GQL Fetch Hook - Improved GQL request error handling so failed token requests preserve original request bodies and return proper response objects.

PiP / Popout Recovery - Fixed multiple Picture-in-Picture and popout recovery bugs that could leave playback in broken or stuck states after ad recovery.

Stale Channel Guard - Removed an outdated stale-channel guard that could cause brief ad flashes when returning to a previously viewed channel.

M3U8 Error Handling - Fixed silent M3U8 processing failures that could allow ads to leak through without triggering recovery.

Ad Marker Detection - Unified ad marker detection into a single shared logic path, eliminating inconsistencies between different detection routes.

Changed
Channel Switch Speed - Removed a blocking cached-playlist validation request during channel changes, reducing unnecessary switch delays and making channel navigation noticeably faster.

[6.2.9] - 2026-04-12

Added
New Achievements - Added Diamond (block 10,000 ads) and Globetrotter (block ads on 50 channels) achievement badges, bringing the total to 12. Fully translated across all supported languages.

Fixed
Post-Ad Re-Entry Loop - Main ad detection now relies only on primary stitched ad markers and explicit known ad segment URLs, preventing stale residual metadata from falsely triggering a new ad cycle after ads end. A 5-second grace window after ad-end reloads adds extra protection against false re-entry.

Ad Recovery Backoff Stability - Exponential ad-recovery backoff now resets correctly on channel navigation, ad cycle completion, and when ad blocking is turned off, preventing delays from growing indefinitely across multiple ad cycles.

Midroll Detection False Positives - Explicit midroll detection now matches only quoted MIDROLL JSON values, avoiding false positives caused by unrelated URLs or text containing the word midroll.

Player Startup Crash Guard - Added protection during early page load so player detection no longer throws errors before extension state is initialized.

Initial State Declaration - _AdRecoveryConsecutiveFailures is now defined during initial state setup instead of being created only after first use.

Route Segment Consistency - Added the missing video reserved route entry so VOD routes are parsed consistently and no longer risk being misidentified.

[6.2.8] - 2026-04-12

Fixed
Midroll Recovery Fix - Native PlaybackAccessToken requests now stay pinned to the forced recovery player type whenever token rewriting is enabled, preventing midroll refreshes from slipping back onto Twitch’s ad-marked path before ad recovery takes over.

[6.2.7] - 2026-04-12

Changed
DOM Cleanup Scope Reduction - Removed the broad anti-popup and overlay DOM cleanup runtime to prevent interference with ad blocking. The extension now relies on playlist interception, playback recovery, and the narrower post-ad display-artifact cleanup path.

Build Validation Cleanup - Removed obsolete helper aliases and stale route-context validation tied to the deleted DOM cleanup path.

Streamlined Popup UI - Removed the separate DOM Ads Blocked counter for a cleaner popup layout; all ad blocking activity is now reflected in the main Ads Blocked counter.

Achievements Update - Reduced the achievement count from 12 to 10 for a tighter milestone set.

[6.2.6] - 2026-04-12

Fixed
Ad Recovery Loop Fix - DOM-driven player recovery no longer loops indefinitely when all backup player types return ad-marked streams. Recovery attempts are now capped per ad cycle with exponential backoff to prevent rapid-fire reloads that disrupt playback.

Fallback Stream Promotion - Ad-marked but playable backup streams are now retained as fallback candidates for ad stripping, ensuring the worker always has a stream to clean instead of returning nothing when every backup path serves ads.

Emergency Playlist Fallback - When no fresh backup stream is available, the processor now falls back to the last known clean backup or native playlist to help keep playback alive during difficult ad windows.

Ad Recovery Backoff Reset - Exponential recovery backoff now resets when an ad cycle ends, so each new ad cycle starts with a fresh recovery budget.

Turbo Lower-Third Shell Cleanup - Hidden Turbo and lower-third display-ad seeds are now correctly mapped back to their player wrappers so stale shell layouts collapse even after Twitch hides the inner ad node.

Faster Visible Turbo UI Suppression - Strong visible in-player Turbo and display-ad signals now bypass the old shell-confirmation delay, reducing visible flashes before cleanup occurs.

Shell-Only UI Recovery - UI-only recovery once again responds to real player-shell ad states even when Twitch does not expose visible CTA or banner copy, preventing the player from getting stuck on ad shells.

DOM Fast-Path Hardening - Forced mutation scans now ignore hidden residue and already-collapsed extension-owned artifacts, reducing repeated DOM churn after cleanup.

DOM Cleanup Counter Stability - The immediate-shell cleanup path is now limited to strong visible ad UI signals, reducing false DOM cleanup counts caused by stale layout residue after navigation.

DOM Counter Consistency - DOM Ads Blocked now only counts persisted cleanup types, preventing recovery-only reload signals from drifting away from popup and stored totals.

SDA Iframe Cleanup - Stream display-ad iframes are now detected by ad host URLs, allowing video-based SDA overlays to collapse even when embedded outside the lower-third shell.

Selector Indentation Fix - Fixed display-ad selector constants with incorrect scope indentation.

hotfix

[6.2.3] - 2026-04-11

Fixed
Playback Monitor Resiliency - Playback-intent and live-buffer monitors now idle instead of stopping during temporary context loss, and automatically restart on ad detection, toggle changes, and route resyncs to help prevent playback stalls.

Route-Less Player Surface Recovery - DOM cleanup now stays active whenever Twitch still exposes a real player surface, even if the URL no longer carries a normal playback route, so cleanup and recovery do not go inactive on route-less player views.

Bridge Counter Queue Hardening - Pending Ads Blocked and DOM cleanup stat updates are now coalesced and retained more safely during temporary bridge outages, reducing dropped counter updates without letting the queue grow unbounded.

Post-Ad Recovery Speed - Reduced the native-recovery confirmation window to a single clean probe with a shorter cooldown, speeding up the return to native playback after ads.

Continuous Post-Ad Reloads - In-place stripped-ad recovery is now treated the same as backup and fallback recovery so the player reloads reliably at the end of an ad cycle.

Playlist Cache Tightening - Shortened the reuse window for stale clean playlists, greatly reducing the chance of the player getting stuck on a lower-quality backup state after an ad cycle.

Minimal Requests Ad Leak - Fixed an edge case where an ad-marked backup playlist could still be selected during minimal-requests fallback.

[6.2.2] - 2026-04-11

Fixed
Popout / PiP Playback Handoff - Opening Twitch’s popout player now pauses the original page player and suppresses automatic visibility, ad-recovery, direct-player recovery, and buffer-recovery restarts on the source tab. Picture-in-Picture and failed popout launches also no longer leave the main player in a broken or duplicated playback state.

Popout Playback Context Recovery - player.twitch.tv popout windows now resolve playback context from query parameters, so popout playback opened during active ad blocking can finish recovery and return from the backup stream normally.

[6.2.1] - 2026-04-11

Fixed
Low-Latency Playback Regression Fixes - Fixed worker bootstrap so the new low-latency playlist helpers are available at runtime, added clean recovery for part-only stripped playlists, shortened stale reuse windows for part-only cached playlists, and extended the ad-entry warm-up path to cover low-latency media entries.

[6.2.0] - 2026-04-11

Fixed
Low-Latency Ad Entry Hardening - The worker now detects and strips ad-marked #EXT-X-PART and #EXT-X-PRELOAD-HINT playlist entries, reducing brief ad flashes before the backup path fully takes over.

[6.1.9] - 2026-04-11

Fixed
Prefetch Ad-Hint Hardening - Once the worker enters an ad-stripping path, it now removes Twitch low-latency prefetch hints as well, reducing intermittent cases where ad media could still be prefetched and leak into playback.

[6.1.7] - 2026-04-11

Fixed
Tab-Switch Pause Regression - Visibility and focus handling now guards playback more actively across tab changes, reducing cases where Twitch pauses the player when the tab loses focus.

Faster Post-Ad Native Reload - Reduced the ad-end grace window and native recovery probe spacing so validated backup and fallback ad exits return to the native player about 50% faster while keeping existing safety checks in place.

Hidden-Tab Resume Retry Parity - Background-tab playback guards now retry through the same primary-media resume path used by the immediate visibility handler, reducing cases where a hidden tab stayed paused until it became visible again.

Firefox Native Recovery Path Parity - Firefox now validates the same forced native PlaybackAccessToken player type that it reloads into after an ad break, avoiding wasted probe cycles on Twitch’s ad-marked site path before switching back to popout.

Tighter Ad-End Timing - Tightened Firefox’s ad-end confirmation window to one clean playlist plus two quick native recovery probes, making post-ad returns noticeably faster while still keeping a minimal safeguard against false-positive reloads.

Backup Playlist URI Normalization - Firefox backup media playlists now convert segment, key, map, and prefetch URLs into absolute paths before returning them to Twitch, fixing black-screen and spinner cases where a clean backup playlist was selected but its media URLs were invalid in the active request context.

[6.1.6] - 2026-04-10

Fixed
UI-Driven Midroll Recovery - When Twitch shows clear in-player ad UI but does not expose a suppressible direct ad video, the extension now forces ad-recovery player reloads instead of letting the main player remain stuck on the ad path.

Safer Live Ad Recovery - The worker no longer short-circuits ad-marked live playlists through the CSAI fast path, so live midrolls still use full backup-stream recovery instead of being misclassified as metadata-only ads.

Broader Player Ad Copy Detection - Player overlay detection now recognizes more Twitch ad-related copy, including Subscribe for ad-free viewing, improving live ad signal detection before and during recovery.
