The Firefox team has huge initiative to fix memory issue called MemShrink[1]. One of the devs blogs regularly about it[2]. I don't know much about this Health Report and memory leaks, but one the blogs on MemShrink said that to fix memory issues (leaks and memory bloat), they needed to measure what and how Firefox is using memory. There is now an about:memory page the gives a great breakdown, though it is very dev oriented and easy to copy/paste into bugs. One of the big items that caused memory leaks is plugins. With FF15[3], made a change to find a very common type of leak with plugins that and free that memory. If you haven't tried seriously FF in the past year, then give it another go. It is much better.
