Steps to reproduce:

On Windows 10, the contrast is very weak also on mouse hover. Please see the Delete button and the Delete checkbox.

I verified on https://dev.fxprivaterelay.nonprod.cloudops.mozgcp.net/accounts/profile/ and the only issue with the contrast for key navigation and mouse hover is now on the Delete button. Please see the screencast:
