Deflr Video Downloader

DEFLR pages often hide the final video URL behind player scripts, encoded payloads, or API responses. Browser right-click save typically does not reveal the actual media file or quality variants, and manual network inspection is tedious for casual users. Generic web downloaders may miss DEFLR-specific API or embedded player paths entirely.

Deflr Downloader solves this by working directly on the active DEFLR page. It checks live media candidates from multiple sources, filters out noise like ads and thumbnails, and presents only the playable options. The extension adds a download button to the player interface, supports the right-click context menu, and handles both direct MP4 and HLS streams through an in-browser pipeline. No remote servers, no copy-paste workflows, and no digging through page source.

How it works

• Install the extension from the latest release.
• Open Deflr and go to a supported video page.
• Start playback so the extension can detect the media.
• Open the popup or use the on-page controls.
• Choose the quality option you want.
• Start the download and wait for the MP4 export to finish.
• Save the final file locally.

Supported formats

• Input: Direct MP4 URLs, KVS-style API MP4 variants, and HLS/M3U8 streams when exposed by the page or player
• Output: MP4
• Saved files use MP4 so they are easier to replay on standard media players, move between devices, or archive locally.

Troubleshooting

• No download button appears on the player Refresh the page, make sure the video is playing, and check that the extension has permission to run on deflr.com.
• Only one quality option is available The extension shows what the source exposes. Some pages may only provide a single stream.
• Download does not start Check your browser download settings and make sure the extension has the downloads permission enabled.
• The extension does not detect any media Press play on the video first. Many pages only expose the stream after playback starts or after player scripts finish loading.
• The context menu option is missing Right-click on the page or directly on the video element. The option appears only on supported DEFLR URLs.

Notes

• Only download content you own or have explicit permission to save
• An internet connection is required for downloads
• Always press play on the video before using the download features
• Available quality depends on what the source page exposes
