First public release since v1.0.5 (2022). Total rewrite of the extension.

Highlights

New architecture

• Full MV3 migration on Chrome and Firefox

Revamped popup

• THIS TAB / OTHER TABS / Recent sections with sticky headers
• Per-download progress card, ETA, byte readout
• Recent downloads list with one-click re-mux / re-transcode and Change Format dialog
• Click thumbnail or title to jump back to the source tab

In-page download UI

• Download button injected on every YouTube watch page with format and quality picker
• Per-playlist panel on the homepage and on playlist pages
• Live progress ring + cancel/restart

Download capabilities

• SABR adaptive-streaming bypass on Chrome (direct) and Firefox (via ANDROID_VR InnerTube client)
• Iframe-scrub fallback for IP-rate-limited videos
• Per-video format and quality selection
• Multi-track audio (dub languages) and embedded subtitles
• YouTube Music cover-art embedding for music tracks
• Playlist downloads as individual files or ZIP bundles
• In-browser mux and transcode via FFmpeg-WASM (no external tooling)

Linux compatibility

• Multipass VM workflow for reproducing Linux-only Chrome bugs
• Fix for issue #11 (tabId < 0 on Linux Chrome dropdown / panel)

Install

See README for one-click .crx (Chromium) or .xpi (Firefox) install. Auto-update kicks in from this release onward — future versions roll out without user action.
