Can confirm, doesn't work on Pop!_OS 22.04 too. I use multi account containers too, haven't tried it without the multi account containers.

I have the multi-account containers extension installed, but I'm not even trying to open a page in a container when the Cloudflare failures occur., I'll be using the default container.

Firefox 129, Fedora 40
