Browser memory usage at startup

Ever wonder how much memory the various browsers are using when they start? Well Chrome has a nice feature from the address bar... Type in about:memory in the address bar and press enter. If you did like I did and started the 5 top browsers before entering about:memory you will get a display something like below:

This display had to be refreshed one additional time in Chrome so technically it shows using more than it really was by about 1mb. As you can see the more features available the more memory is being used. IE8 is surprisingly the stingiest in memory. I was surprised that Opera used so much memory but I guess with all the extra features like voice it needs the resources.
Please note I took caution to start each browser in a blank page to ensure no extra load was recorded for memory usage. Each browser was started only once beforehand.
