Twitch Followed Streams by Bill

To watch a stream, hover its thumbnail, which will display 3 buttons (1st screenshot) :
- "Twitch" : open the stream on Twitch in a new tab
- "Video popup" : open the stream video in a popup
- "Chat popup" : open the stream chat in a popup

The "Channels" tab displays all your followed channels. Click on the name of a channel to browse its videos.

The extension can display a notification when new streams start if you enable the option in the settings. Notifications can be enabled only for some channels.

The extension uses the Twitch API which require authentication with your Twitch account.
