Not able to install extensions from official website
Solution 1:
Things you need to check before trying to install the gnome-shell extensions.
- You need to have a fully updated gnome-shell and all its libraries (as the message on the site says).
- You should be using Firefox web browser (The site currently doesn't support Google Chrome and other web browsers).
If you still cannot install any of the extensions, try resetting GNOME configurations to the default settings.
- How do I reset GNOME to the defaults?
