Just an idea:

Log out/in, check memory usage is normal.  If not log out, restart /etc/
init.d/xdm and login again.  Start FF without any addons.  Use a new profile 
if necessary.  Check memory usage.  If after a while under normal use you 
still have reasonable levels of memory usage, then you can start adding one 
add-on at a time and see where that gets you.

You may also want to give youtube-dl a spin.  I know, it's not a FF-GUI video 
download tool, but it works without getting in the way or eating up RAM 
unnecessarily.
