[codedokode]

It is bad because if browser uses too much memory then it swaps out other programs like gnome-shell to the point that you cannot use Alt-Tab because the code responsible for it got swapped out.

It would be better if poorly designed sites (for example newspapers or TV channel sites) were slow or displayed without images and iframes with ad rarher than situation when browser swaps out everything else to help this poorly designed site run faster.
