What's new in 4.46.2
- Downloads: fixed the Cobalt fallback and folder picker (both were silently failing).
- SponsorBlock: no more stale segment bars or wrong auto-skips after switching videos.
- Subscription Groups: corrected "Shortest first" ordering and a stray new-badge bug.
- Transcript: correct timestamps past one hour (
1:02:40, not62:40). - Userscript: finds the download companion on its fallback ports; sturdier CPU-saver.
- Popup: clearer screen-reader errors, keeps keyboard focus when toggling, friendlier size/number formatting.
