Firefox does some HEAVY caching and that eats RAM like it's free. But
that aspect should only be on the server side. The TC should not see it.

Hmm. Unless firefox is using the xserver to manage caching...

I have firefox open (not running a TC environment) and xorg has ~98MB
and firefox has ~109MB. I opened another firefox window and loaded up a
bunch of new tabs with different web pages with graphics and my xorg
went to 118MB and firefox went to 115MB. It looks like it is directly
accessing the xorg process.
