Steps to reproduce:

1. In about:config, I set privacy.resistFingerprinting to true.
2. I connected to my virtual private server console using NoVNC provided by the hosting service
3. I rebooted the server and entered grub console
4. I tried to enter some special characters that can be typed using Shift+number, e.g. ~!@#$%^&*()_+

Actual results:

The characters were typed as if I didn't have Shift pressed, i.e.
`1234567890-=

Expected results:

The expected characters should have appeared:
~!@#$%^&*()_+

This looks like the keyboard layout protection is causing problems. Although I haven't see this issue before, this looks like it should work.

Could you provide your operating system, locale, and keyboard layout?
