What does it save?

Porn4days Video Downloader collects the video stream that the Porn4days player loads and stores it on your device as an MP4. The player can hand over a direct MP4 file or an M3U8 playlist (the HLS format, which splits a video into short segments), and the extension recognises both. Whichever arrives, the extension takes care of the MP4 conversion, so every file you keep is an MP4 that plays on nearly any device or media player without format worries or extra software.

Quality is decided on the Porn4days side. The resolutions you can pick from are the ones the player exposes during playback, and every variant the extension detects is listed for you to choose.

Why can't the browser save it on its own?

Porn4days puts each video inside an iframe, a player nested within the page. The page itself is little more than a shell, and the media lives in that inner element. Before you press play, the stream address does not even exist on the page. Right-clicking the video or using basic save tricks therefore has nothing to work with.

The extension attaches itself to playback at the right moment. As soon as the player requests its stream, it identifies the downloadable media and keeps it before the player takes it in. Everything happens in the browser, with no outside tools and no copying of links, and the browser's own download engine writes the file. It is built for Porn4days specifically, which lets it reach media that ordinary tools miss.

Where does it run?

• The porn4days.pw domain.
• Standard video pages whose address follows /video/<slug>.

Search results, category listings and homepages are outside its scope, and on those pages its toolbar icon looks inactive. It will not work on other platforms at all. Until a supported page loads it runs quietly in the background, so its footprint stays small.

How do I use it?

Install the newest release in your browser. On Porn4days, open a video with /video/<slug> in its address, wait for the page to load fully, and start playback so the player initialises. Then click the extension's toolbar icon. The popup scans the page, and once detection finishes it presents a tidy list of streams with a download button beside each. Choose the quality variant or format you prefer, start the download, and pick the place on your device where the MP4 should be saved.

Access to the extension uses an email sign-in. A one-time password confirms it, so there is no password to remember.

What can stop a download?

DRM-protected or otherwise restricted videos may not be available, and some Porn4days videos use a different player configuration that the extension cannot detect; testing a different video tells you whether the extension is working. A connection that drops mid-download can leave a broken or empty file, which a page reload, fresh playback and a second attempt usually solve. If nothing starts at all, check that the browser allows downloads, that a security setting is not blocking downloads started by extensions, and that storage space is available. Finally, if Porn4days updates its player infrastructure, the extension may need a matching update.

Respect content ownership and only save videos you are authorised to keep.

FAQ

Is every Porn4days video page supported?

The extension is tuned for standard video pages that follow /video/<slug>. Search results, category listings and homepages are not part of what it handles.

Why does nothing appear until the video is playing?

The Porn4days player only loads the real stream after you press play; before that, the media address is not on the page at all. Starting playback is what exposes it for the extension to capture.

Is there a way to get a resolution the popup doesn't list?

No. The choices depend entirely on what the Porn4days player exposes during playback, and the extension already shows every quality variant it detects.

Can I point it at a site other than Porn4days?

No. It is designed around the page structure of Porn4days and will not work on other platforms.

The popup opens but lists no downloads. What should I check?

Confirm you are on a real video page with the /video/<slug> pattern and that the video is playing. Press play and try the popup again.
