Useful, but needs some more features Rated 4 out of 5 stars

Very useful add-on. The only thing I wish was added was the ability to only time on certain sites. You have the feature to NOT time on certain sites, but that is not what I am looking for.

The reason this would be useful is so that I can keep track of time when on Facebook and other time-wasting websites.

Of course, being a programmer myself, I simply added this feature, but if you added it to the actual add-on, I think many people would be happy with it.

Other than that, it is a great add-on!
