Use this page when the extension is installed but not behaving as expected. Start with the basic checks first, because most issues are caused by an old extension state, a stale browser tab, or a page that has not been reloaded.

​
Extension not working after install or update

1

​
Refresh M3U8 Download Web Page

https://pro.m3u8.dev/ is the main page for M3U8 Downloader Pro, and it needs to be refreshed after the extension is installed or updated. Open the page and reload it to make sure the extension is properly connected to the page.
2

​
Refresh the target page

Reload the page where you are testing the extension, then start the video again.
3

​
Reopen the browser tab

Close the current tab, open it again, and test once more.
4

​
Reinstall the extension if needed

If the extension still does not work, uninstall it, install the latest version again, and reopen Chrome.
If a video shows a playback error in the popup, try playing another video that works first, then go back to the original video and play it again. The same workaround can also help when downloading.

​
Test M3U8 Downloader Pro with a known working page

Here is a simple example you can try:
  1. Open https://x.com/NBA/status/2033047587419279799.
  2. Click the M3U8 Downloader Pro button in the browser toolbar.
  3. Select a video in the popup, then play it or download it.

​
No stream is detected

If the extension opens correctly but does not detect a playable stream:
  • Start the video first so the M3U8 request has a chance to appear.
  • Wait a few seconds and check the extension again.
  • Test another page to confirm whether the issue is page-specific.
  • Keep in mind that DRM-protected content or hidden playlist requests may not be supported.

Still need help?

If the issue continues after the steps above, contact support@m3u8.dev and include a short description of the page, the browser you are using, and what you already tried.
