GNOME Shell integration doesn't work with snap version of Firefox

[David D Lowe]

In Ubuntu 21.10, the default installation has been switched from the version provided by APT, to the version provided by snap. Users that upgrade from Ubuntu 21.04 to 21.10 will be migrated to the snap version of Firefox.

In the snap version of Firefox, it is impossible to install extensions from https://extensions.gnome.org . This error message is displayed:

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

Installing chrome-gnome-shell does not fix this issue.

I'm not sure where to file this bug report exactly, but I thought I would file it here.
