Making the text larger in Firefox 3 for Windows

Change the text size temporarily

To increase or decrease the magnification of a web page in Firefox, press Ctrl and '+' (plus) to zoom in or Ctrl and '-' (minus) to zoom out. To return the page to its original size, press Ctrl + 0.

You can also do this via the menu bar. Click on 'View' and then 'Zoom' in the drop-down menu, as shown in Fig 1. Or press Alt + V and then press Z. If you want to only change the text size rather than everything on the web page, make sure 'Zoom Text Only' is ticked. You can tick or untick it by clicking on it or by pressing T.
