Hmmm, FireFox 48 has died: its name only appears in the menu bar. Force Quit removes it (but doesn't mention it is inactive). Reloading it achieved nothing. Nightly has sucked its guts out, so I better be happy with that...
[some console details supplied below]
As for my experience of the Tate, its main page (
https://www.tate.org.uk/) has a couple of pics, but these are really ads - details of artwork with type over. The remaining 30 pictures are blank grey rectangles.
Searching the collection (
https://www.tate.org.uk/search or
https://www.tate.org.uk/art) gives 16 grey blanks.
Clicking an entry (e.g.
https://www.tate.org.uk/art/artworks/turner-two-women-with-a-boy-and-a-small-child-d00831) gives a large grey blank, plus 15 additional suggestions, also grey blanks. Looking at the page source, the actual illustrations are embedded as ordinary html tags for jpg files of different sizes (lines 368-372, again 1748).
These can be viewed using their hidden URLs; the only time the image appears is when "License this image" is clicked (line 414). A medium sized picture appears, marred by their ugly logo.
The different browsers for Snow Leopard yield the same result. All in all - useless for searching the Tate collection. Similar problems have cropped up on sites for other major galleries across the globe. I reckon their web designers went feral during covid lockdowns.
As promised, here is the epitaph for FireFox 48:
