To make it temporarily bigger, click on "View" in the menu, then choose "Zoom" & in there it will let you set the zoom to bigger or smaller.

If you want to make it permanently bigger, if you have a Mac, choose "Firefox", then "Preferences"/ if you have Windoze choose, "Tools", then "Options" (both look the same from here...), then click the "Content" icon & change the font size.

That should do it...

You can use an extension to set a default font size and page zoom on web pages.
