This extension can block websites you entered, so you won't get distructed while doing sth. productie. It's mainly written because I wanted to learn some JavaScript. (Explains this code) Try it out: [https://chrome.google.com/webstore/detail/web-blocker-dont-get-dist/ilnmbhfflemmohnfkflbajbkapkfkgag?hl=en-GB]

Clean the code
Add material tables to the blacklist site
Overwrite search function and/or how I save the data, to save performance
Design the pop-up window

I will eventually upload this extension to the chrome Store. If you want to, you can test it already. Just download the zip and import it in Chrome.
