Firefox Memory Leaks

How much will it leak if you do... nothing at all.

After frequently needing to kill FF when it consumes over 2GB of RAM (I´ve seen 3GB and 4GB sometimes) I figured a little test was in order to see just how bad the memory leak problems are in the browser.

As an experiment I left FF running overnight after a fresh start to see just how much memory would be gobbled up when the browser sat there untouched - The resulting task manager captures speak for themselves.

over 300Mb for doing - nothing at all. That´s a bit much in anyone´s book. It´s sad to see my favorite browser seemingly going down hill as it get´s "enhanced" but there is hope - a new team is supposedly working specifically on the memory leak problems - let´s hope that can cut this down.

Notes:
This is Firefox 5 on a Windows 7 64bit system with core i5 2500K + 16Gb RAM
During the test there were 10 tabs open in panorama but none with anything like flash or video in them.
