Yep
Especially useful for people with old or very slow computers, or prefering to surf with blocked javascript. Blocking CSS speeds up snail pages enourmously (when even JS block doesn't suffice yet), and sometimes it even unhides stuff that otherwise wouldn't be visible without JS.
Had badly missed this function for YEARS, and only recently learned it has existed all that time already, even in KM1.6! Kinda fell off the chair ...!! :O :O
And of course immediately started creating a macro to get a menu...
And there are a bunch more of those handy "permissions.default.xxx" prefs, also for iframes ("subdocument"), also long since missed. Really wish there'd be a native KM user interface for them, but then again, wish this for a hundred prefs...
For occasional use one can simply toggle such a pref in about:config page.
If anyone wants to toggle very often, here some macros:
Macro "Priv3buttons" (on-off-no3rdParty) creates toolbar buttons to toggle some of those default permissions:

Macro "Permdefs" (stupid name, meant default permissions) toggles the same by a menu:

FF Addon "ExExceptions" is a great interface for geckos native BLACK-WHITE-lists, to define certain domains as exceptions of those global permissions:

Macro "Blockeria" is a helper macro for mass-toggling of several global prefs at once. It's for advanced users who can put together their own groups of self-chosen prefs. Out-of-box it includes only a few prefs as *example*, by no means complete, with red, yellow and green buttons for toggling (or by menu):

Those 4 I'm now using very happily all the time
