GNOME shell extension doesn't work with snap version of web-browser

Question

Got an error from Firefox saying :

Although the GNOME Shell integration extension is active, the native host connector is not recognized. Please consult the installation manual.

Which is an error that seems to never happen, I'm using Ubuntu 18.04 (Dual Boot Windows 10), and yes GNOME shell is installed via

sudo apt-get install chrome-gnome-shell

I'm using Firefox v64.0.2 (64 bits) snap.

Could someone help?

Solution 1

You don't need to install extensions from extensions.gnome.org as they are also available in 'Ubuntu Software' app.

Launch Ubuntu Software, click add-ons, click extensions tab. Here you are able to install extensions.

Solution 2

Since you're using the snap version of Firefox 64.0.2, it's not unexpected given various restrictions of snappy.

This issue is already raised in snapcraft forum: https://forum.snapcraft.io/t/firefox-snap-is-unable-to-access-chrome-gnome-shell-connector/4562, but unfortunately no solutions were provided there.

Similar issue can be seen with the Chromium snap too: https://forum.snapcraft.io/t/chrome-gnome-shell-does-not-work-with-chromium-snap/3377/2
(see the bug-report)

64.0.2 (64 bits) - ( I removed the one that come with it (but it didn't worked either at the time) for the newest ) . And yes i'm in a GNOME session : it echoed ubuntu:GNOME

In Ubuntu 21.10, by default, the snap version of Firefox is installed, although you can easily uninstall it and switch to the APT version of Firefox.

Perfect, a bit messy interface to search in (no ranking) but as said by pomsky, hope they'll correct their bug. Thank you !

This appears to be the only viable solution in Ubuntu 18.04 currently. Thank You!

There is no "add-ons" in Ubuntu Software for Ubuntu 21.10 anymore
