build 2001080203, Win95 Mozilla memory usage monitoring using SpyGuru: a. After opening a new window (or use reply or forward) for the first time and then closing it, memory usage is increased by about 3.8MB. b. By subsequently opening and closing more composition windows, memory usage is also increased (270-330Kb for every window). Memory is returned to the system, after shutting down Mozilla (can I call it leak then?). It is NOT returned to the system after closing Mail&News in turbo mode. This makes turbo made unusable after prolonged operation, particularly in memory constraint systems (64MB ram).
This has been fixed very recently but not until after the build you're running was created. The patch didn't land until a few hours ago. See bug 87040

Yes, it's a dupe of 87040 and the fix really works! Memory does not increase anymore.
