It’s time to throw away greedy Firefox

A quick quiz for today. What application that ate 1,3 GB of my memory and 50 % CPU I forcefully ended in the Task Manager to give me such a picture?:

Yes, Mozilla Firefox. What I dared to do? Download 3 files 300 MB each in size. Apparently Firefox Download Manager holds them in the memory until it downloads them and only then flushes them to disk! Complete fail. I had to switch to the Internet Explorer 8 to download them all (without any problem).

(Yes, I know about 3rd party download managers, I use one of them, but not for such small files.)
