Finalizationregistry is part of (well, technically, very closely related, but definitely in the same scope as) the WeakRef API. It offers a callback when a specific value gets garbage-collected in JS.
This (letting web content reach in and control/monitor internal engine mechanisms) is a monumentally bad idea.
We don't have it, nor is there any intent to implement this.

I think at this point you're much better off using Chrome for Discord (not even Firefox, especially if you're using its WebRTC where screen sharing a tab + its audio is only possible in Chromium). I myself have a pretty beefy laptop and no matter how much clock I put into Pale Moon, Discord is simply just unusable with its constant repainting of the viewport. Even Facebook is usable despite all its bloat... (provided I have my laptop plugged in to AC power for the CPU turbo)
I have Discord run under
SubWebView's separate NPAPI process when I'm not using WebRTC, only resorting to a full-fledged Chromium (Edge in this case though I have been looking at Vivaldi) when I am in a watch party (where I sometimes share my screen).

I wonder if this is part of googles progressive web application push. PWA being another way to chromium monoculture, getting rid of adblockers, and getting telemetry. What with browsers becoming OS's, programs would be sites.

Off-topic:PWA was initially pushed by Apple and Mozilla. I think PWA does have its legitimate uses. News sites for example could just leverage their own website as the "app" for offline reading instead of separately writing a whole new native application in both Android and iOS (and I'm not even getting to the point of publishing your app yet). I also remember when Twitter used to have a lightweight PWA that was more usable than the native Android version (and adblocking still works if you have Firefox which was still Fennec internally at the time I believe as the browser). We also still support an early PWA technology that the mainstream dropped in favor of Service Workers which is the
HTML5 cache manifest.

A pity this modern NPAPI is only for Windows! The chief reason I keep Ungoogled Chromium around is for Discord’s sake. I have considered moving my Discord use (beside voice and video sessions) into Pidgin for a while, yet have not dared to make this plunge. I remember using Discord within Pale Moon up to 2021 or so. The site looked outwardly the same then as it does now. How does it degrade so much under the bonnet?

I always found using the browser version of Discord to be a slow, buggy mess.
Just download the desktop app. Trust me, you'll save yourself a ton of headaches.

Discord in Ungoogled Chromium 104 has always run smoothly enough for me. My question about what has been happening to Discord’s codebase is meant to be more general, not a request for technical support, for the same trends surely affect lots of other sites even worse than Discord. Meanwhile, Discord’s own ‘desktop version’ condemns itself in my eyes on two counts. I reject installing any software which forces automatic updates or which simply simply embeds a website in the manner of Electron.

Discord doesn't force automatic updates. On the app version, a tiny green arrow will appear on the top-right corner of the screen whenever an update is available. You can choose to ignore this arrow if you wish, and it will not draw attention to you to click it. It's not intrusive.

If this is so, then Discord’s software has, contrary to my original post, got better in at least one way since 2019 or 2020, the last time I tried the desktop version, and my only objection is my general rule against desktop applications which are really just websites. (This also encouraged my switch from Tutanota to Posteo, among other things.) Thank you for informing me!
