This is a great idea. For a long time I wished I could watch the memory consumption of add-ons in a simple and clear way. Using the build in "about:memory?verbose" and try to read the add-on memory is simply too hard.
A more compact view of the list would be great. Especially if you use a lot of add-ons (30-40 in my case). But that's just my personal wish.
Well done! Thank you very much for this useful add-on.
