And yet another extension broken by the WebExtension update. Even though the settings import doesn't work any more from previous versions, I managed to configure the icons (though it was a bit buggy), but now when I try to click on them in the app's popup window, nothing happens. Rolling back to the previous version for now. Firefox ESR 52.5.0.
Thanks a lot for reporting! This should be fixed in the latest versions. If you are still dealing with this issue, please let us know at https://apps.jeurissen.co/g-app-launcher/contact
