Ah firefox. I know the Mozilla guys have been doing sterling efforts 
banishing memory leaks. I think ff9 (I'm using 10 here so can't check) 
has about:memory with the advanced reporting of memory usage.

about:memory
about:memory?verbose

You will see each tab/page listed as individual compartments with the 
amount of memory that is attributed to that. They are still working on 
apportioning all of the remaining memory (on my system heap-unclassified 
is 30%) but it should give you clues as to particular pages that may be 
causing the worst leaks.

A good geeky read is Nicholas Nethercotes' blog 
http://blog.mozilla.com/nnethercote/ where he talks about the Mozilla 
MemShrink project. They have just started looking at how best to detect 
leaks in plugins so there might be something related there.
