I find the about:permissions to be super useful and I actually use it more
often than the page info dialog.
It seems like you could build a [hosts -> permissions] table from
[permissions -> hosts] even when you might get strange results sometimes
with https://google.com, http://google.com and/or mail.google.com. This UI
is only for advanced users anyway.
I am totally against removing this UI before we have a centralized
Honestly all those changes required for about:permissions seems to be
get/set code looks almost identical to above. The rest is some bookkeeping.
The observer registration/removal code could be simplified a bit.
Copy and paste from above, with fullscreen changed to push.
Same change three times, why is that not one file?
