imgur.com renders and then changes to an almost-empty page
In Tor Browser 10.5.5, https://imgur.com/ renders all the pictures and then switches to a nearly-blank page. (It's not entirely blank, because there is still a little 'privacy' tab in the bottom right.)
It's almost like it runs some sort of javascript detector to see if you can handle its site, and the detector gets confused by something in Tor Browser.
I think the site worked in Tor Browser 10.5.3, so maybe something changed in Tor Browser, or maybe something changed on the website side.
