Rated 4 out of 5 stars

I find this add-on extremely useful to help me keep track of things that need upto date information on each refreshes, like stock market sites, and several e-mail accounts.

**note** do not load more than 5 pages of 9 (45 sites) with each site reloading at different intervals. I found on my setup, there was alot of background activity that caused my caret to loose focusing while doing mundane things such as webmail. Other than that, this add-on is amazing. I even have it keeping track of grocery shopping flyers !!! :D

This review is for a previous version of the add-on (0.7.2.5).
