How can you make the font of messages from those big bold ones to thinner ones? Please help me.

Ctrl and - or +

You need to hold ctrl button down while pressing either - or + to increase or decrease the size of the text on the screen. As a warning, this pretty much does it with the whole page, so pics and possibly flashes and vids shrink and grow with it as well. Hope this helps :3
