I need some more information about an issue, so here's a general question: does the media files load up for you at https://mementomori.social on Firefox? Personally have not yet been able to reproduce. Using Cloudflare R2z
The issue: https://github.com/mastodon/mastodon/issues/33640
@rolle On the Moshidon app, the images work fine. When I use my desktop, Firefox Nightly, images appear as broken and never load. I try on private window and they also don't work.
I tested it on someone else's computer, with normal Firefox and half the images aren't broken.
@rolle I keep thinking it might have something to do with what extensions are plugged in, but I haven't had time to test that theory out ^^;
Edit: just saw your latest update post--I'll test my FF when I'm home!
@rolle I forgot to reply yesterday but--all the images now pop up wonderfully on my end! I'm so glad to see them fixed! Thank you for your hard work 
@vsitante Cool! Thank you for your report, I'll test later on today myself as well on the problematic Linuc machine.
