media-cache allows you to cache and later download the content that is streamed using the MediaSource API. Adding a website To add a website to cache, click on the extension and write the hostname. Note that you need to follow a specific syntax to add the URL. For example:

*://*.example.com/*: both for HTTP and HTTPS, cache every video that is played from the "example.com" domain
https://ex.example.com/*: cache only videos played from the "ex.example.com" domain
https://example.com/page: cache only videos that are played from that specific page

Downloading the files: After playing the resource, you can choose from a Select in the popup the page whose video/audio content you want to download. Click on the "Download" button to download them. While the download of the videos should automatically start when the page is closed, or when the video ends playing, it might not always work, so it's suggested to download them directly from the extension popup.
