Tested on Firefox 62.0 and Waterfox 56.2.2, Windows 7 64bit.
The toolbar icon of version 0.13.0 used to show the list of domains when clicked on, even when the address bar icon was disabled in the extension options. This has changed with 0.13.1, it's only showing "Cloudflare not detected." now when clicked on if the address bar icon is disabled in the options, but the badge with the number is still here showing correctly non-zero Cloudflare requests on the toolbar icon.
