memory

I use Mozilla Firefox 3.6 all day, opening and closing tabs quite regularly. I am noticing over time that the firefox.exe process size keeps growing and growing over time.

Initially I put this down to memory fragmentation caused by opening and closing tabs, but now I am suspecting that there is a memory leak in one of the add-ons that I have installed.

The problem I am seeing is that when the process size gets to about 1.5GB in the "Mem Usage" stat in Task Manager (and it gets there quite regularly), Firefox freezes up.

Does anyone have any ideas about how I could diagnose whether:

Any of the add-ons are leaking memory?
Something else is causing this problem?
