Another Manjaro big update.
Side note: on the first boot after the install, the Unite extension doesn’t load and so it is the case for Firefox’s settings. Either reboot the computer or refresh the desktop by pressing Alt + F2, write “r”, press enter. Or close Firefox and open it again. We do not know what causes this bug but it is easily fixable by simply restarting the computer, desktop, or Firefox. And it will work after that.
