People have already noticed[1] and started flipping layout.display-list.retain to test it. To help our triagers / diagnosticians on Bugzilla, it might be a good idea to put that pref in the about:support whitelist so that we know if it's been flipped by the user.

This sounds like a good idea.

Bug 1411288 - Add layout.display-list. to pref whitelist for about:support

The attached patch whitelists the whole layout.display-list pref tree, since the dump prefs have a very negative impact on performance if enabled.
