Firefox for Android should let me change the default font size without needing to change the Android system-wide font size -.-
I know I can set the minimum font size in about:config, but this messes up website styling.
When I increase Android's font size and check Accessibility -> Use system font size, the font scaling is ok.
But this solution is not good - now fonts are big everywhere in my phone... It seems simple to add a font-size slider, and I think it's a saner option.

Maybe look for an extension.
