Fire fox is hogging mem usage.

more options

Firefox is using a ton of memory it shows it is using between 300,000k and 700,000k under Mem usage in Windows Task Manager. Why is it hogging/leaking so much memory? Is this a known problem? I am up to date on everything. so can anybody help me fix this?
