Now Playing 作者： Suyooo

Grab the current title of video or music playing in your Firefox and put it in a text file on your PC.
Made primarily for streaming, so you can have a "Now Playing" overlay if you use your browser to play music.

Important: For this extension to work, you need to download a desktop application. Head to github.com/Suyooo/firefox-nowplaying for details and instructions!

What the permissions are needed for:
- Exchange messages with programs other than Firefox: Allows the extension to send the media information to the desktop application, which handles configuration and writing the files to your disk.
- Display notifications to you: To let you know about the extension's status and errors.
