Clean URLs, hidden player layer

On JustPorn, every video gets a page of its own at a neat address of the form /video/<id>/<title>/. That part is simple. The catch is that the video isn't served through an ordinary HTML video element: an embedded player stands between the page and the real source and fetches the stream while it starts up. Tools advertised as working everywhere tend to read only the page markup, which is why they so often come up short on JustPorn.

Justporn Video Downloader works with that player rather than with the page source. It spots the /video/ address pattern, attaches to the embedded player as it loads, follows the player's media requests and then shows you the stream options it caught. Open a video, click the extension, save: that's the whole routine, and there's no hopping between tools.

Main capabilities

• Recognises JustPorn video pages from the shape of their URL
• Watches the embedded player during initialisation and catches the stream it asks for
• Finds segmented M3U8 playlists, which let you choose a quality
• Grabs a direct MP4 when the player hands over a flat file
• Shows each detected stream with its quality level in a tidy popup
• Keeps all processing on your computer, collects no data and never contacts outside servers
• Stays out of sight during normal browsing and uses very little on tabs that aren't JustPorn

Usage

1. Add the current release to your browser and sign in with your email address and a one-time password.
2. Open a JustPorn video page and check that its address follows the /video/<id>/<title>/ form.
3. Wait until the page and its embedded player have loaded, then press play. The player asks for its stream only after playback begins, so an empty popup almost always means the video hasn't started yet.
4. Click the toolbar icon. The popup lists every M3U8 or MP4 source picked up from the player.
5. Pick a quality and start the download. If only one option appears, that video simply exposes a single stream variant; the popup always shows the full set the player provides.
6. Once the MP4 is saved, play it in VLC, QuickTime, Windows Media Player or whichever player you prefer.

What you end up with

The sources are either segmented M3U8 playlists or plain MP4 files coming from the embedded player, and the saved file is MP4 in both cases. It needs no conversion to play on a desktop computer, a phone or tablet, a smart TV or a media server. If your default player has trouble with a file, VLC Media Player supports the broadest range of MP4 formats.

Where it works and what it needs

Detection is limited to JustPorn's /video/ pages. Listing pages, category pages and search results aren't supported, and an address that doesn't match the video pattern won't activate the extension at all. Stay connected for the length of every download; M3U8 transfers in particular break off when the network drops out, so steady the connection and try again if that happens. Only download videos you are legally allowed to keep.
