this extension work out-of-the-box. this will measure exactly how much time you spent on the f*ckin boring facebook web page and those other bullsh*t page :) thanks in advanced!

Thank Paul, I works awsomely!

Reliable tracking and beautiful, simple summaries

Very useful time tracking app!

Absolutely awesome. Also gives statistics about past weeks and day. Great tool.

It's very useful add-on :D, i would like new function where i can entry a list of domains on which work this addon any time when open thoese sites because i anytime forget start video mode on youtube

It's perfect to REALLY realize how much time you spend on the web.

Stop working a couple of days ago. But in general it was very good.

It tracks all the durations, it has the option to whitelist some sites and the reports are neatly presented.

I can only wish this great Add-on could keep track of several computers for a single account. Sometimes you have to be aware of your time at home and at the office.
Keep up the great job your doing!!!

Excellent add-on, simple and just works! Please add an option for a blacklist, some people like me just want to track time spent on a few sites, not every the internet. Thank you million times!

great addon, the statistics are very useful
