about: chrome: redirection dont work

[dezhavu]

Hi,

about:haoutil Rule doesn't work , just says Invalid URL.

I also tried to make this rule, but it doesnt work either:
name: "chrome:// to view-source:",
from: /^chrome://(.+)/i,
to: "view-source:chrome://$1",
regex: true

Any solutions?
Firefox 63.0.3 x64, win10

Thanks
