Hi,
i am currently trying to set up a new machine to control my robot through the GCC. I am using a freshly installed Ubuntu 20.04 LTS with Firefox and Brave Browser. I installed the browser certificates according to https://docs.motorcortex.io/docs/getting-started/connect-your-pc/linux-install-a-browser-certificate/
However, i am unable to either access the controller gui via the controllers ip-adress in the browser, nor access the motorcortex.desk. I am able to ping the controller and to log onto the controller via ssh.
We've had the same issue accross multiple devices in the past. On my current machine, i can access the controller via browser using chrome and firefox, the desk however only by using Edge or Brave.
Attached a screenshot of the browser console with firefox from the new machine.

Regards,
Gianni
