onyx is not installed message (But it is!)

[computer-wizard]

Firefox version 116.0.3 OS: Ubuntu 22.04 The latest Overbite extension is installed from the Firefox web page. Onyx is installed in /usr/local/sbin/ and onxy.json in ./mozilla/native-messaging-hosts/ of my home directory.

When I open my gopher page I get the following message in Firefox,

Onyx is not installed OverbiteNX requires the Onyx native component to access Gopher sites.

Install Onyx for your operating system from [Github](https://github.com/classilla/overbitenx/releases).
Reload this page.

But Onyx is installed and the path in onyx.json is correct!

{ "name": "onyx", "description": "OverbiteNX Gopher system component", "path": "/usr/local/sbin/onyx", "type": "stdio", "allowed_extensions": [ "[email protected]" ] }

Location onx,

ls -l /usr/local/sbin/onyx -rwxr-xr-x 1 root root 35488 Aug 20 16:05 /usr/local/sbin/onyx

This did work perfectly in previous Firefox versions.... I did compile and installed a new version of Onyx but this didn't help
