Opening "Account" crashes the client

[robertmaxton42]

Clicking on the "Account" icon opens a panel saying "You are not logged in. Please try the following methods", but the panel is blank. More critically, doing so makes the client unresponsive; the panel cannot be closed or switched to another tab, and so the current proof cannot be continued or exported.

(Judging from the debug notes in the console, I suspect this is a known bug, but I didn't see an existing issue on the matter so I'm opening one now.)

.... Okay, so part of the problem is that uBlock was blocking some Firebase features ^.^;. I'm still leaving this issue open, because I think the app should fail more gracefully than a crash that loses your work, but it's at least half my own fault.
