I installed Debian 9.1 with KDE and Chromium. In Chromium there is a built-in extension called "GNOME Shell Integration" that I cannot remove or disable (it is "installed by system administrator", which is, in theory, me). However, I do not use GNOME, and package
chrome-gnome-shell is not installed according to Aptitude. If I go to the extension's options, it says: "Although GNOME Shell integration extension is running, native host connector is not detected", which is correct.
How can I get rid of it?
