My Ubuntu Gutsy was being really slow today and I thought I would check my Process Manager. Looked at my memory usage and it was at 99% and 99% of my swap had also been used 
I thought maybe I just had too many apps running and started closing some stuff down, nothing made much of an impact. I then closed Firefox and my memory usage dropped from 1.8GB to 800MB. That's a 1GB drop!
I knew Firefox had memory issues but I have never seen it that bad :/
