I was using LeechBlock to keep me on the right path when I should be working: it blocks sites you tell it, during the part of the day that you tell it; still great, for distracting sites.
But for YouTube, a total block can get in the way of some work-related videos; whereas this extension will allow for search. Just removes the ability to see suggested videos, which tempt you to drift away with them. Very good!

super effective thank you!!

Great, sad the pro version it's expensive ($5/month)

The LinkedIn news feed is a psychological warfare operation

5$ a month for a project that any college student can complete in 1 day? Use "News Feed Eradicator" guys, it's wonderful

Considering buying it, excellent add on!

First add-on I've paid for, and it's worth it.
