I had this problem until I changed /etc/login.conf default class to use datasize-max=7000M: and datasize-cur=7000M and rebooted. I have 8GB RAM and haven't tried lower values yet for datasize-max and -cur. I am using only three extensions: 1Password X, Firefox Containers, and UBlock Origin. For me, 1Password X will not work until I disable UBlock Origin and then restart Firefox. I then sign in to 1 Password X. At that point, I can re-enable UBlock Origin and everything works. The problem started with 1Password's new version 1.17.0. This workaround does work on all my -current machines. If I go to about:debugging# and This Firefox and UBlock Origin, I see "WebAssembly.Memory failed to reserve a large virtual memory region. This may be due to low configured virtual memory limits on this system." I don't know how to fix this, and my increased datasize-max and -cur don't change this. But if UBlock Origin starts before 1Password X, my guess is that this memory error stops 1Password X from working. As a side note, I have to start Firefox from the Downloads folder if I want to be able to upload files from it.
