I just don't understand this. Furthermore, I don't know if I've ever seen a "scientific" test of FF vs. Chrome using real world apps.

At work, I have several GUIs in browsers that I access through Chrome, and they cause instant 3+ GB of usage. I can't test FF due to group policy, but anyway, Chrome can be a hog, too.

Are you saying that those same half dozen apps, when pinned in Chrome, do not cause any RAM issues for you?
