Do not import Gdk and Gtk in extension.js (line 9 and 10). Importing Gtk in extension.js isn't allowed until you don't have any other options. Use spawn command to open url: `xdg-open URL`. 3. Remove Lang, Atspi and Meta imports (extension.js). 4. Please remove unnecessary logs (line 79 and 882 extension.js). 6. Also null out `this.settings` in disable. 7. Don't name a function `spawnCommandLine` when it's not clearly doing that (line 686 extension.js). 8. Remove the timeouts on destroy or disable (line 298, 325, 691 extension.js): https://gjs.guide/extensions/review-guidelines/review-guidelines.html#remove-main-loop-sources If you need any help with your extension you can ask us on: - [GNOME Matrix Channel](https://matrix.to/#/#extensions:gnome.org) - IRC Bridge: irc://irc.gimpnet.org/shell-extensions
