Interesting Firefox Hack for Clearing Memory

I was talking to a co-worker today and he mentioned that there was a Firefox setting, in about:config that would make Firefox release all it's used memory if it was minimized. This sounds very nice. So here's the deal: pull up about:config, look for the setting config.trim_on_minimize and if it's there, make it 'true'. If not, then right-click in the main section of the preferences and add it.

Restart, and you're done. Pretty neat.

I've got it set up on my work Firefox, and we'll see if this allows us a little relief on the JavaScript memory usage. I'm hoping it does because then when it's minimized, it's out of the way. That would be very nice.

UPDATE: you have to minimize all Firefox windows in order for this to kick in. Not exactly hard, but you have to remember to minimize everything. Nice to have in your pocket if you have things like the Google Visualization widgets on your pages.
