How do you set the size font as a default?

[tximacusr]

I see that when I open either one of my browsers, I switch between Firefox and Safari, the font is very small and I have to use CMD and the plus (+) key to increase the font.

How do I permanently keep it at a bigger default font? Thanks.

Application Menu (i.e. Safari or Firefox), open preferences, then modify the Standard font in the Appearance section.
