1. Click on the "hamburger icon" on the top right (looks like three horizontal dashes). 2. Select the option "Options". 3. Scroll down the settings page until you see the option "Fonst and Colours". 4. Select the font you desire and you can click on "Advanced" for further tweaking. You could uncheck the option to allow pages to choose their own fonts, instead of your selections.

Hope it helps.
