YouTube No Chat: Take Back Your Screen

This add-on automatically disables the Live Chat, and has a simple, easy to use interface. Instantly turn Chat back on if you feel like chatting during a live-stream without ever reloading, or set it to disable Live Chat on full screen only.
You'll never be bothered with clicking "Hide Chat" on every video ever again. YouTube No Chat handles all the clicking for you, so you can enjoy your favorite live-streams without interruptions.

Features:

• Live chat is hidden by default when you open a live stream
• Toggle chat on/off from the popup
• Switch between "always hide chat" & "only in fullscreen"
• Preferences are synced across browser instances
• Lightweight code: Runs instantly without slowing down your browser

PLEASE NOTE: I ported this add-on from the Chrome Web Store. I rewrote all the .js files to call Firefox APIs, but the credit for the original code goes to the named developer below.
