Great! Rated 5 out of 5 stars

This is an excellent tool. I love that I can still browse my favorite websites but without guilt because I know that the time will be within my reasonable pre-set limits. I can see all kinds of ways to use this tool to be more effective (for example to allow myself to ONLY access the website I need to get my work done).

This review is for a previous version of the add-on (0.4.3).
