I have Firefox 67.0.2 (32-bit) portable and a new Firefox Quantum 67.0.2 (64-bit). The problem exists in both browsers. I have enabled cookies, but it didn't help. In the portable version, the only enabled extension is an ad blocker. The new Firefox is still clean, with no extensions installed.
New Firefox:

Another question about the avatar: I think I installed and enabled it, but it doesn't appear next to the messages.
