Thanks for your feedback. Here are some steps you can take to troubleshoot:

1. Clear Cache: Sometimes, cache issues can cause problems. Try clearing your browser's cache.

2. Check Autoplay Settings: Look into your browser's autoplay settings. You can do this by searching for "autoplay" in the browser's settings page. Ensure that the option to block audio and video is not enabled.

3. Use an Ad Blocker: The extension works correctly only when an ad blocker is enabled. I recommend using "uBlock Origin," as it has been tested successfully.

4. Disable Other Extensions: If you're still experiencing issues, it might be due to another extension. Try temporarily disabling other extensions to see if that resolves the problem.
