My Favorite Add-On Rated 5 out of 5 stars
Firstly, I signed up for an account just so I could write a positive review for Leechblock. I originally downloaded it on my PC when I was having a hard time getting through a huge project I needed to finish (took a few months). I found myself procrastinating every possible way, and this program was EXACTLY what I needed to control it, since it is made for people who procrastinate and not just people who want to block sites for other reasons (eg. parental control).
After I switched to a Mac I was sad to lose the program. I initially searched through the firefox add-ons without specificially searching for Leechblock and it didn't come up. I even did a google search for a firefox site blocker and it still didn't come up. I only found it when I was looking through a forum and someone recommended it) and I was so excited to be reminded of it. I downloaded it right away and I'm thrilled to see that it's the same great program I had before, and it's compatible with the latest version of Firefox.
This is an outstanding add-on, perfect for anyone who wastes more time than they should on the internet while they should be working.
