The memory cache on my system becomes larger than its maximum value according to
<about:cache>.

Reproducible: Always

Steps to Reproduce:
1. View <about:cache>.
2. In other tabs, use Mozilla.
3. Look at <about:cache> tab.
4. Repeat step 2 and 3 as necessary.

Actual Results:  
Eventually, the "Storage in use" indicator for the memory cache device has a
larger value than "Maximum storage size".

Expected Results:  
The cache should not become larger than its maximum size.

I did not find a duplicate searching for "memory cache".
In preferences, I clicked Clear Memory Cache.  I then refreshed <about:cache>
and it did not seem to do anything.  The Clear Disk Cache option does work.

I am adding the perf keyword since memory usage is related to performance.

worksforme mostly with linux trunk build 20021123
disk/memory usage did not exceed the max size
clear memory cache decreased the memory cache from 4M to 1.5M
clearing disk cache decreased the disk cache from 20M to 0

footprint is the keyword you're looking for.

I updated to 2002112607 and the clear memory cache button works and the memory
does no become larger than its maximum.  Marking WORKSFORME.
