Mozilla's idea behind adding this new page was to make detection of zombie compartments as simple as possible. Zombie compartments are a kind of memory leak. In previous versions, you had to use about:memorypage to find out zombie compartments which was a little bit complicated but now addition of this new about:compartments page makes it easier.
