Or use a script blocker like NoScript or uBlock. These offer significant 
security benefits and significantly reduce memory footprint.

May need to use xhost to allow the second user access to the X server, 
something like this:

xhost +SI:localuser:myffuser
sudo -u ffuser /usr/bin/firefox
xhost -SI:localuser:myffuser

It's not an issue on a single user box; it's the same user (human) with 
a different UID.
