New: configurable keyboard, mouse and wheel shortcuts, plus named playback profiles (global or per-channel) on both sites.
YouTube: transcript and chapter workspace; local subscription collections with feed filtering.
Twitch: automatic player recovery with a visible cancel, live-edge button with delay indicator, sidebar favourites/groups/search, and a theater/fullscreen chat overlay.
Settings: search, Basic/Advanced views, themes, presets, import preview with selective merge or replace, automatic pre-reset backup, seven-day undo, and redacted diagnostics. Optional Firefox Sync covers lists and folders.
Fixed: the previous video's title could stick to the watch page after an end-screen navigation when DeArrow titles were enabled.

SponsorBlock, completed: a shield button on every video's player opens a panel to create segments (mark start/end at the playhead, nudge by half-seconds, test the jump locally, pick a category, submit) and to vote on existing segments; the post-skip notice gains a Report button next to Unskip. Migrating from the official SponsorBlock extension? Paste your user ID into the options page and your reputation carries over.

Player buttons are now flat SVG icons that match YouTube's own (no more mismatched emoji), and they dock into YouTube's new sectioned control bar, fixing icons missing on some videos. SponsorBlock skips now show a 7-second notice with an Unskip button that jumps back and stops auto-skipping that segment.

4.3.0: opt-in community data - SponsorBlock segment skipping (per-category, with progress-bar markers), DeArrow community titles/thumbnails, and Return YouTube Dislike counts. All off by default, no new permissions. 4.2.0: playback speed suite, audio compressor, A-B loop, screenshots, comment filtering, Twitch tag/rerun blocking, chat highlight/block filters, deleted-message reveal, emote tab-completion, stream uptime, sidebar hover previews.
