GNOME Shell extensions not working in Ubuntu 22.04

I followed the instructions on to install GNOME Shell extensions, but I still get the error:

Although GNOME Shell integration extension is running, native host connector is not detected. Refer to documentation for instructions about installing connector.

The current version of the browser Firefox is packaged as a snap version. One of the issues with this is that it cannot work with the Gnome Extensions website.

The current work around is to install a desktop application that allows to search for and install extensions.

Look for "Extension manager" in the software store, or install with a terminal command:

sudo apt install gnome-shell-extension-manager

This article may help you:

from what i understand, the apt/deb file just refers back to the snap version, so the ppa instructions at that link should get you the non-snap version. Hope this helps. Good luck!
