Reduce Firefox memory usage

Here's a trick to help reduce the amount of memory used by Firefox when it is minimized. It only works for Firefox on Windows. But when you use this it'll free up almost all of the memory used by Firefox when it is in the minimized state.

Go to the address bar in Firefox and enter about:config

If you are using Firefox 3, you may get a warning. Just skip it.

Once you get shown all of the preferences right-click in the main part of the page and select New > Boolean.

Enter the name as config.trim_on_minimize

It'll then create the preference and the value will be set to false. Double-click on the entry and the value will toggle to true.

You need to restart Firefox for the change to take effect. But once you do Firefox will give up almost all of it's physical memory when it is minimized.
