Thank you! Rated 5 out of 5 stars

I often check site images in Firefox, because it displays its dimensions in the title. In my case just now I needed to know, if images have a black border... which I could not tell anymore, because the background was pretty much black itself. While 'centering' might 'look nice(r)', it sort of takes away a quick intuitive check for an actual image's size - esp. if it has transparent padding.

Agreeing with the recent commenters. This ridiculous obsession with higher
Versions and the need to literally 'bugfix' new undesired behaviour with add-ons is slightly getting out of hand. This add-on - too - made me finally sign up here.

So big thanks for this add-on.

This review is for a previous version of the add-on (1.0).
