I love Firefox, but it does hog system resources more so than IE. There are two improvements that can boost your overall system performance. These changes will make a noticeable difference!

On average Firefox takes up more than 60 Megs of Ram.

Reduce Firefox’s RAM Usage for Its Cache Feature

1. Type “about:config” (without quotes) in the address bar of your Firefox and press Enter.
2. Find “browser.sessionhistory.max_total_viewer”
3. Set the value to “0” (Zero)

Cut Down Ram Usage to 10 MB when Firefox is Minimized

1. Type “about:config” (without quotes) in the address bar of your Firefox and press Enter.
2. Right click in the page and select “New” > “Boolean”
3. In the pop-up box that appears, enter “config.trim_on_minimize” and hit Enter
4. Select True and press Enter.

There are many add-ons that I run in Firefox, that use system resources. If you aren’t using an add-on, it’s best to turn it off.
