Gnome Top Panel Transparency

Googling didn’t reveal any help. Trying to make the top panel transparent, I know how to using Ubuntu, but nothing works using Suse.
going to extensions it show this error “No such native application org.gnome.chrome_gnome_shell”

@verndog Did you install the Chrome gnome shell integration? GNOME Shell-Integration - Chrome Web Store

This one? Transparent Top Bar (Adjustable transparency) - GNOME Shell Extensions

Yes, as shown above. Going to your link I get “No such native application org.gnome.chrome_gnome_shell”

$ sudo zypper up chrome-gnome-shell Loading repository data... Reading installed packages... No update candidate for 'chrome-gnome-shell-10.1-1.56.x86_64'. The highest available version is already installed.
As seen I have the latest “chrome-gnome-shell”

@verndog can you try epiphany or firefox instead?

I am using Firefox.(for some reason I need at lest 20 characters to reply)

@verndog So if you visit GNOME Shell Extensions does it ask to add the integration? Or in Activities overview search for extensions and open that to see if it works.

Then you need the firefox extension (and not the chrome one): GNOME Shell-Integration – Holen Sie sich diese Erweiterung für 🦊 Firefox (de)

As you can see, its installed, but I still get the error message

i found the problem. The installed version works, but if I install from mozilla and install to “/opt” it fails. Strange though Ubuntu works this way.
This way fails:
