You are the shadow that casts itself

Tonight's links, a strange_selkie two-fer:

Peter Cushing as Mr. Darcy, BBC 1952.

That is definitely the youngest I've ever seen Christopher Lee.

handful_ofdust, I feel you should know about this.

What is the matter with you, kid?

And now for something completely different. As of this evening, LJ appears to have ceased to display icons on either my entries or my friendlist. Not mine, not anybody else's, not in comments unless they're in the user's own style. I did a complete refresh on Firefox in case that was the problem and it wasn't. Has anyone (who is still using LJ) experienced this problem? If so, do you have any suggestions? In an ideal world, by morning this issue will have fixed itself and I can delete this post. We do not live in an ideal world. I'd love advice. Icons are important. This one should have a very cranky-looking Psholtii at the top of it.

[edit] Since it's started to come up in comments, I run Firefox 46.0.1 on Mac OS 10.6.8. The latter of these has not changed in years. (Please do not encourage me to solve any problems by updating my operating system; I have several technical reasons for holding on to this version.) Looking at Firefox's release history, I can't see that it's done anything in the last twenty-four hours. I am therefore assuming that the sudden non-display of my icons is a problem with LJ, but would appreciate correction if I have the wrong end of the hydra here. In the meantime, my journal continues to look very naked to me.

I hope I don't have to change the style. I have had Refried Paper since I started this journal in 2004 and I'm used to it.

[edit edit] Experimentally reverting to Firefox 45.0.2 on another computer with the same operating system, my icons become visible. Updating to Firefox 46.0.1, my icons disappear. I don't understand why this issue did not make itself obvious on April 26, 2016 according to the online release history, but there it is. I can see in the HTML for the page that the icons are present, just not displaying. So: toxic Firefox/LJ interaction?

[edit edit edit] It looks like an HTML compliance issue with LiveJournal. It's just showing up now in Firefox. This is almost certainly out of my control.
