I can post a pic that shows opera using 22,376k and firefox using 33,124k, both with four tabs opened. However, I won't because it doesn't prove anything. Your pic doesn't either. The memory usage of a web browser can be manipulated pretty easily. With a few seconds of trying I was able to get both firefox and opera above 40 mb of ram usage, which is higher than either normally use on my system. Normally, I'd let this go, but don't post a misleading pic then accuse people of lying.
