I installed Gnome Ubuntu and when I try to install extension (going to extension.gnome.org from the tweak tool) i get the error "We cannot detect a running copy of GNOME [...]" I tried to go on their troubleshooting page but i wasn't able to solve my problem. Any idea what my problem is and how I can solve it?
1: you have to be running firefox to install extensions. IDK of any other browser that will allow you to install extensions.
2: when you go to the web page with firefox, there will be a little popup tab in the top right hand corner of your screen. It will ask you about permissions or something like that. You just gotta click ok and then refresh the page. It SHOULD work then.
Sometimes I have to close firefox and then log back in.
If you have any other problems, please refer to this page.
