I have a Debian Jessie 64bit 8.7 and Google Chrome Stable 57.0.2987.110.
When I visited the GNOME Shell extensions site, I saw the following information:
Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector.
On Firefox ESR (Mozilla Firefox 45.6.0) , I got the following error:
ReferenceError: chrome is not defined
I can't install any GNOME extension because of it. Should I install chrome-gnome-shell? It is in stretch and sid repositiories, not in jessie. Should I change browsers?
