If the Menu Bar is already showing (with items such as "File", "Edit", "View", etc.), it's pretty easy: View --> Text Size --> (and take your pick from the 5 choices)
If the Menu Bar items aren't already displayed, I think a right click up "near" the top of a browser page should bring up a little menu--just check "Menu Bar" there.
