Centering is awesome --- before this I had to use a Stylish style to centre images ( which is as it should be in all browsers ); but Mozilla's new black background is insane: thanks to this excellent add-on one can have a neutral grey, or any other colour, plus centering...

This review is for a previous version of the add-on (2.1.1-signed.1-signed).
