I have tried logging out and logging back in on my android firefox. accounts.firefox.com shows it is logged in, yet I do not see my firefox on android listed in my "Tabs from other devices"/"Synced tabs", in fact, I do not see any other device tabs listed. On my android firefox, it shows that I am logged in, yet the checkmarks for choosing what I want to sync are all disabled, the sync now button can be clicked but does nothing. I have tried logging out, forced stopping firefox app, and restarting android, nothing worked.
