So I've tried changing the default font size all across the board, but it doesn't seem to have any effect on webpages. Am I doing something wrong here?

I have not noticed any changes on sites I visit by changing the font sizeSSSS. I don't know if it actually works or not.

I think the font size has more to do with what you type than how websites render on the Playbook. It is like on your phone. I use comic sans, but websites don't render in it, only my native stuff.
