I recently upgraded to Ubuntu 21.10 and found that the browser addon for installing Gnome extensions doesn't seem to be working with Firefox. I get the following error when I visit https://extensions.gnome.org/:

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

I have installed chrome-gnome-shell but it doesn't work. It was working just fine on previous versions. I suspect that it may have something to do with Firefox being packaged as a Snap by default in 21.10.

Does anybody know a fix for this problem?

It's because when you installed/upgraded to 21.10, the Software Updater uninstalled your previous .deb version of Firefox, and installed a SNAP version of Firefox.

There are two possible ways to fix this...

  1. Start the Ubuntu Software application and search for "Firefox". You'll find two of them. One will show as installed... that would be the SNAP version. Uninstall it and install the other (.deb version of) Firefox.

  2. Or, using the command line in terminal:

    sudo snap remove firefox

    sudo apt update

    sudo apt install firefox
