Rated 3 out of 5 stars

Finally somebody that makes looking at about:memory fun. But please show MB instead of KB. 29000.43KB is not very readable whereas 28.32MB is much better and 28MB even better.
Four stars if you change that. Five stars if you get to something like Win8 taskmanager. :)

This review is for a previous version of the add-on (1.0.1.1-signed.1-signed).
