Didn't work for me Rated 1 out of 5 stars

I installed it and I don't think anything changed. I'm not sure if there's somewhere you're meant to set the list of websites, but I tried facebook, twitter, wikipedia, reddit and there was no difference. I restarted firefox to be sure. Maybe I'm missing something.

You My Friend Saved My Life From Procastination Rated 5 out of 5 stars

Goodness gracious, I've been working my way through my History project, when suddenly I've got a feeling to go to Facebook, even though I've been doing my project for only 5 minutes! OK, readers you gotta admit that it would happen to ya, so the next moment you are starting on your project, the other moment you "magically" went Facebook or Twitter. This simple extension saved my life by making me think twice on my disastrous actions. Thank you!
