NoDistractions - website blocker от AsciiJakob

Use if: You just want a simple extension to block distracting websites when enabled, an extension that has an intuitive and convenient UI.
Don't use if: You require the extension to be toggled during specific times of day, or you just generally prefer more advanced and powerful features with the trade-off of simplicity.

Features:
- Sites are easy to add and doing so requires just two simple mouse clicks, you don't have to navigate through confusing menus.
- The ability to temporarily visit a website (for just a minute or two) is available. It's possible to toggle this feature off in the settings, for those with bad impulse control.
- Blocking can easily be toggled on or off through a popup. A keybinding is also available (CTRL+ALT+D).
- Advanced site patterns (using URL Match patterns) are available for users with more specific needs (see the help section of the popup).
- The extension is open-source, meaning that i am not afraid of hiding the code behind the extension and i allow users to contribute to it if they want to implement a feature.
