Todobook

Turn the Facebook News Feed into a todo list so you can stop wasting time and start getting things done.

Also works for LinkedIn, YouTube, Reddit, Twitter, Product Hunt, and Hacker News.

Once you've completed all your todos you can use News Feed again. If you need a break, you can disable Todobook for the day via the Todobook icon in your browser's toolbar.

Todobook DOES NOT access, read, edit, or store ANY of your data on Facebook, and never will. And it will NEVER post anything to Facebook on your behalf. It also requires access to your navigation history so that it can detect when you're on facebook.com. It DOES NOT read, transmit, or store any browsing history, it simply detects your current url.

Tip: You can configure the break time, the frequency of breaks, and you can turn on 'work hours' via the gear icon in the top right of the extension UI once you've loaded facebook.com. If you turn on 'work hours', the extension will only be active between 8am and 6pm, Monday through Friday.
