Firefox has gotten to be a real memory hog

I am sure most any user of Firefox has noticed in the last few months that it has gotten to be a real
memory hog.

I have been looking for ways to decrease memory usage and release old memory and came across a new one
on me that I want to share with whoever else has not heard of it but has memory bloat problems from the
application.

enter "about:memory" in the same way you would enter "about:config"

click on "minimize memory usage". A rollover will disclose what it does.
