After install KUbuntu 24.10, I've uninstalled Firefox snap and add the mozilla repository for installing Firefox with apt.

Firefox is installed, but appears the message "some of Firefox’s security features may offer less protection on your current operating system". Reading the link provided in the message, I've created the firefox-local file on /etc/apparmor.d/, but continues with the same error. The Firefox path used is /usr/lib/firefox.
