Firefox sometimes blocks sites that expect a Chrome browser, but the Chrome Mask extension disguises it as Chrome and works automatically on chosen domains.
Occasionally, Firefox users encounter websites that refuse to load unless Google Chrome is installed. The same site will run perfectly in Firefox if the restriction is bypassed.
There are several ways to do this, but the simplest is installing the Chrome Mask extension, which masks Firefox as Chrome with a single click.

To avoid toggling the extension each time, you can list the domains in its settings where it should activate automatically.
