best way to install Gnome extensions?

edit

A bit more details, if anyone interested.

To make matter even more confused, is Software you can two entries for one extension - but they will have shown different sources: fedoraproject.org and extensions.gnome.org.

So, basically, you have three ways to install gnome extensions.

1. Using website. This is gnome-provided distribution and package manager agnostic way of installing extensions. So it would be the same in Fedora, Ubuntu, OpenSuse, etc. You just need support in your browser, as was mentioned earlier. Extensions will be installed for current user into ~/.local/share/gnome-shell/extensions/ directory (in home. When they'll be updated on gnome website, your browser will notify you and ask you to update your local copy. If you have multiple users on your machine, each have their own selections of installed extensions and has to update them separately. That's the way I prefer to do it (for most extensions).

2. Using Software application and choosing packages with sources extensions.gnome.org. As far as I know, it basically does the same as installation from website, but is specific to Software application, i.e. if you use some other graphical package manager you may not find such an option (depending on manager's support of this feature). I think I've never seen Software asking me to update my extensions as I always keep them up to date through my browser, but I think it should notify you of updates.

3. Using Software and choosing fedoraproject.org. This is equivalent to using dnf from command line. This way you'll install an rpm package from Fedora repository packaged by one of Fedora package maintainers. It's different from numbers 1 and 2 in three ways:

4. Extension is installed system-wide, i.e. for all users of this computer (although it can be enabled/disabled individually by each of them). It's installed in /usr/share/gnome-shell/extensions/.
5. Extension can be updated only by user with root access using Software of dnf in command line. Updates are system-wide. Updates are available only when rpm package maintainer updates the package, and applied along with other system updates.
6. Extension can be different from extensions.gnome.org variant: can have different version, can also contain some Fedora-specific patches, if it needs them.

And a bit of trivia about extensions installed by default in Fedora: as far as I know they are needed by Gnome Classic desktop mode available from login screen. I've never tried to update them from the website.
