Good add-on Rated 5 out of 5 stars

This add-on is MUCH EASIER than going to about:cache and converting the kilobytes to megabytes.
Instead, it sits on your add-on bar and tells you the size of your cache in a more "friendly" unit (MB).
And, for those of us with small screens, allows a more compact mode.
Nice job.

This review is for a previous version of the add-on (0.7.10.1-signed).
