Prevent Firefox from Hogging Memory When Minimized

Got this tip off of Lifehacker.. Head on over there to hack life better.. :)

Heres another handy little tip for those of you who are low on RAM. You could prevent Firefox from taking up RAM when it's minimized into your taskbar.
Just like earlier, all you need to do is only enter a new value in the about:config page.

So heres how its done..
Type about:config into your address bar.
Hit Enter.
Confirm to your browser that you'll be careful messing with your configuration.
Right-click somewhere outside all those period-separated values and choose New/Boolean.
In the window that pops up, enter config.trim_on_minimize
Hit OK.
Then select "True" in the next dialog.
Close out your about:config window, restart Firefox, and you're done! :)
