I have recently downloaded a new font for my computer, I tried to use "tools" to let me see it while I browse the web but it won't change the font at all, I restart Firefox, but I haven't tried rebooting the computer yet because I have an art program that expired and won't save so I have to print screen my drawings, but this program uses layers so it'd be a hassle to paint, thanks for your time and for helping me with this! :)
