Re: increasing font size hangs the emacs

[nakkaya]

you can also set it in .emacs

(defun na-resize-frame-big ()
  "Set size"
  (interactive)
  (set-face-attribute 'default (selected-frame) :height 130 :width 'normal)
  (set-frame-width (selected-frame) 178)
  (set-frame-height (selected-frame) 50 )
  (set-frame-position (selected-frame) 0 1)) 

when you call this function it will make emacs full screen with bigger
fonts. to set a particular font you can use 

  (set-default-font "monaco")

or for firefox like cycling you can try
