Rated 5 out of 5 stars

It should be standard in Firefox. The most important information for me is the download speed. It helps me a lot for instance when I watch streaming video to see if my provider works.

It would be great to be able to set some limits and changing colors. For instance if the Firefox memory consumption goes over a certain level then it should display a bright red - or whatever color you customize. Same for the CPU etc.

This review is for a previous version of the add-on (0.2.19).
