Rated 5 out of 5 stars

I was terribly addicted to twitter, so much so that I almost lost my PhD grant to it. Thanks to Leechblock I managed to use the Pomodoro Technique, therefore giving myself a 5-minute twitting time as a reward for 25 minutes of hard work. I use a similar add-on in another mainstream web browser but Leechblock is far more customisable and flexible, that's why Firefox is now my default browser.

This review is for a previous version of the add-on (0.6.3.1-signed).
