how to disable AI features in firefox 148 at system wide level?

Linux installation

– Open the configuration file and save it (Ctrl+S) anywhere on your computer. Make sure the file is called “policies.json” (without the quotes). – Open a new Terminal window in the directory where the file is located. For example, if it’s in your Downloads folder, open a Terminal and run cd ~/Downloads to switch to the Downloads directory. – Create the Firefox policies directory with this command: sudo mkdir -p /etc/firefox/policies/ – Copy the file to the new folder: sudo cp ./policies.json /etc/firefox/policies/ – Restart Firefox.

To remove the custom configuration, delete the policies.json file from the distribution folder and restart Firefox. You can do that in the Terminal: sudo rm /etc/firefox/policies/policies.json
