ouTube downloads failing with "HTTP 403": some YouTube videos stopped almost immediately with a "couldn't download the file (HTTP 403)" error, most often on music videos and Mix/playlist pages. Save Media now picks a download source that YouTube still accepts, so these videos download in full again, up to 1080p.

Dailymotion — Fix download

Fixed: long video downloads
- Long videos on some sites failed partway through, after hundreds of MB had already downloaded. They now complete.
- Large videos could stall at 75% and lose everything downloaded so far. These now stream straight to disk instead, so the stall is gone.
- Download size and speed could be reported wildly wrong (a 2.2 GB video showing as 11.5 GB). The counter is now accurate.
- The merge step now shows bytes as it works, so you can tell "still running" from "stuck".

New
- The Video tab now shows a short note when you're on a site we haven't tested yet — along with an invitation to try the download anyway. The list of tested sites updates from our server, so new sites are recognised without waiting for an extension update.

Fixed YouTube downloads failing with "HTTP 403"

• AV1/VP9 videos that opened with sound but no picture are now converted to
H.264 automatically, so they play on Macs before the M3 chip.
• The quality picker is now a separate button next to Download and starts on
720p instead of asking you to choose.
• 4K and 1440p on YouTube are selectable (marked "VP9/AV1").
• When a site offers several codecs, the playable one is preferred.
• Firefox: fixed the Delete button doing nothing.

• Files with no picture track are no longer offered as video downloads
(seen on some Douyin clips).
• Audio-only formats no longer clutter the list on regular video pages.
SoundCloud and embedded players are unchanged.
