excellent extension. it feels so good when i can finally get focused on my work and get things done. thank you thank you. what a life saver! my new year resolution is that i can, at some point, internalize this extension, so that even when i use a browser that does not have this extension installed, i will not turn to my list of procrastination sites. it's all about study/work habits, isn't it?

It didn't work. I tried to block a website over and over but nothing changed, and the stupid site I wanted to block still pops up every time I try to open Google Chrome. I followed the steps and everything, I don't know what's going wrong.

Working as it should. Nothing more, nothing less. 4 stars for very uncomfortable UI. Possibility to add web page to blocked from basic view should be perfect.
