Chrome-Stats extension

This extension detects M3U8 streaming formats on the active tab and offers to download these segmented streams as a single file to the user's local disk.

This extension detects all possible video qualities and uses direct disk writing to store segments. So there is no need to have a recovery plan from a possible crash. Your data is written instantly to the local file and is ready to use. It also merges all segments automatically when the file is fetched. To improve download capability, the extension also sets the referrer header of the original page.

This extension uses multiple threads to download the HLS stream to increase the downloading speed and stability. Also, it supports resuming the download process when there is a network failure (Thanks to the TDM.JS engine).

How to use it:

  1. Go to a streaming website like
  2. Wait until the toolbar color changes
  3. Click on the toolbar button once to select a quality
  4. Wait until the download is over. You can see the progress as a badge text.
