Clicking "view source" on an event that doesn't load shows something like this: {

I think the service worker is failing to do its thing. What do you see in the inspector? https://firefox-source-docs.mozilla.org/devtools-user/application/service_workers/index.html#debugging-your-service-worker |
|
The inspector shows "No service workers found". Presumably that is a problem. Here's the output from the console: Console output |

When visiting about:debugging#/runtime/this-firefox, I see:
Visiting about:config, it appears that So the real problem here is that Element does not loudly complain when it fails to start service workers. |

Steps to reproduce
I'm logged into matrix.org via SSO from github.com. In every channel (such as #main:postmarketos.org, aka #postmarketos:matrix.org, but I see this everywhere) attachments fail to load. Image previews just show a spinner, and other attachments do nothing when clicked on.
Image previews (which are missing, just showing spinners) or attachment download buttons.
Outcome
What did you expect?
The attachments to show previews and download when I click the download button.
What happened instead?
Previews never show up; when clicking the download button, an error box pops up saying (for example):
If I middle-click images, I get a page like https://matrix-client.matrix.org/_matrix/media/v3/download/matrix.org/rClrxSFSsjJgaovxRCTZmheM?allow_redirect=true with the contents:
