This useful tweak should of course not have been necessary. It reminds me of Ye Olde Dayes (mid-1990s) before style sheets etc, when A Browser unilaterally decided to use a grey background instead of white for general web pages (or was it the other way around??)
In this present situation, I have hundreds of images of *objects* photographed against a white background, often tightly cropped to save file space. The 'off-black' background now unilaterally applied makes a complete travesty of simple display of these items. (The centring is less of a problem.)
In general, display of 'an image' on a web page is not the same as the display of a video (which is pretty much a self-contained object in itself). Presumably the Firefox people were thinking only of a framed 'photo album' approach... But then, why not use a proper black?
Not thought through, not thought through...
