How to set default font in Mint
by joboy from LinuxQuestions.org on (#6FMK7)
I am running Mint Debian edition, and I set the default fonts to a chinese type, I can see on Thunderbird using it but not in other applications, such as Whatsapp web with Firefox, and Google photo on Chrome using it but not with Firefox, where Signal not web based is using it I am quite confused, I wonder what does 'default' mean, and how to change that if no setting for individual applications ?
