How to precisely find the amount of memory or RAM being used by Firefox

Until today, I relied on system monitor & top to find out the amount of memory being used by firefox. This works fine but there is an even better way to find out the exact amount used by the browser. Visit about:memory page to find it out. It lists out detailed information about the memory used and its distribution.

In Firefox 4 is not working, at least on my system!

I don't remember doing any configuration changes for it; worked out of the box.

Not just this. Chrome even shows the memory usage of Firefox :P

Actually, I guess that's the reason firefox is not able to display it. Some serious locking screwup somewhere :P
