The websites causing the ram issue were the same on both Windows and
Linux.
I generally keep the number external sites connected at one time to a single digit.
I use No Script, and notice that, for many sites, the list of 3rd party sites I have to
"temporarily trust" to make the site usable has grown to the point where I need to
scroll down to see the full list. We need to a list "resource hog" sites to steer
people away from sites that are causing memory issues.
