Although GNOME Shell integration extension is running, native host connector is not detected

This is a bit of a nuisance, after a fresh install of Ubuntu Gnome, I was not able to install extensions from extensions.gnome.org.
Firefox asked me if I’d like to install the extension but after a Firefox restart I still wasn’t able to install any plugins.
To be precise; this message was shown:
Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector.
The solution was to install the chrome-gnome-shell package;

sudo apt-get install chrome-gnome-shell

This fixes the message from both chrome and firefox.

  1. Already had this installed.

    Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    chrome-gnome-shell is already the newest version (9-0ubuntu1~ubuntu16.04.3).
    0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

    Uninstalled it. Installed it again. Still no gnome extensions. The extension is added to the three browsers I have. None can work the gnone extensions.

    1. had any luck with this?

      both my Chromium & Firefox can’t find the native messaging host despite the same install/uninstall process you tried
