Distractions are commonplace. Send you a funny picture on Facebook,check my steemit status..
you must log in to check a certain status for just a moment and more.

sometimes you can control yourself when you are doing it,Especially for people who work a lot in front of a computer independently.

sometimes you can even forget that you told yourself that "I am not going to enter facebook for few houres " and ... BOOM you are in facebook again ADHD hmm hmm..

If you can not overcome these distractions and burn them precious time that should be dedicated to work, Citrus can help.
What the plugin does is block your access to a distracting site for a predefined period of time.

If you enter Facebook at the specified time, you will receive an amusing message from the Citrus team, stating that they blocked access. To please your time, they will give you inspiring quotes, which may cause further distraction, but they can not help beyond that.

I got an inspired quote from The Rav Ovadia Yosef lol I am kidding :).

there is a video how to use this extension
