GNOME Extensions website doesn't find connector

[Michael Weimann]

After updating to 18.10 beta the GNOME extensions website stopped working. I installed the latest Firefox browser addon. But the website still shows "Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector.".

The extensions website also doesn't work in Chrome or Epiphany.

Similar problem here, although the GNOME Integration extension works in Chromium for me. In Firefox, it remains broken.

Ubuntu version: 18.04.2 LTS
Chromium version: 73.0.3683.86 (installed via Software Center)
GNOME Shell Integration version: 10.1 ( installed via https://chrome.google.com/webstore/detail/gnome-shell-integration/gphhapmejobijbbhgpjhcjognlahblep )
Firefox version: 66.0.3 Quantum (installed via Software Center)
GNOME Shell Integration version: 10.1 ( installed via https://addons.mozilla.org/en-US/firefox/addon/gnome-shell-integration/ )

Please let me know if additional info is needed.
