@peder: Yes, the keyboard is set to U.S.
@Danp: No change after Firefox restart.

This just got me, too. No shift nor CTRL when using Firefox, but all keys work fine in Chrome.

• Firefox 75.0
• xo-server 5.56.3
• xo-web 5.56.2

I'm currently having problems with typing in the console of all of my VMs, but only when using Firefox on MacOS:

• keys pressed with the shift key pressed will be entered as if the shift key was not pressed;
• keys pressed with the option key pressed will not be entered at all.

This occurs using Firefox 70.0.1 and also Tor Browser based on Firefox 68.0.3.

This does not happen when using Safari or Chrome. I have not tested this using Windows browsers.

I do not use Xen-Orchestra very often, and the consoles even less often, so I do not know when this started; several aspects of the system - XOA, Firefox, Tor - have likely been updated since I last tried the consoles.

XOA:
