How to make the text larger in Firefox 3 for Linux

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, as shown in Fig 1. Click on 'View' and then 'Zoom' in the drop-down menu. 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.

Click 'Zoom In' or press I to increase the text size. Click 'Zoom Out' or press O to decrease it. (You can also use the arrow keys to navigate the drop-down menu and then press Enter when 'Zoom In' or 'Zoom Out' is highlighted.)

To tell Firefox to use your choice of font size, untick the box beside 'Allow pages to choose their own fonts, instead of my selections above' by clicking on it, or press Alt + A to untick it.

Click on the 'OK' button, or press Tab until it is highlighted and press Enter, to return to the 'Firefox Preferences' window (Fig 1).

Click on the 'Close' button, or press Tab until it is highlighted and press Enter, to finish and return to Firefox.
