Firefox for Apple OS X - Making text larger

Below are the step-by-step instructions on how to increase the font size in Firefox

Note: Mac key convention: ‘Ctrl’ is used for ‘Control’, ‘Apple’ is used for ‘Command’ and ‘Alt’ is used for the ‘Option’ key.

Note: For keyboard access make sure ‘Full keyboard access’ is turned on - you can turn it on or off; by pressing ‘Ctrl’ + ‘F1’ at any time.

Follow these steps to increase or decrease the size of the text for the web page you are viewing:

Click on the ‘View’ menu with the mouse.

Hover your mouse over ‘Text Size’ and choose a different text size from the listed options as shown in Fig 1.

Or use keyboard shortcuts:

Press ‘Apple’ and ‘+’ (plus) to increase the text size and ‘Apple’ and ‘-’ (minus) to decrease the text size.

To set a larger text size for all the pages you visit:

Click to select with the mouse or press ‘Ctrl’ + ‘F2’ to highlight the menu bar and then press the right arrow to highlight the ‘Firefox’ menu.

Click on ‘Preferences’ or press the down arrow to select and then press ‘Enter’.

Make sure the ‘Content’ tab is selected if not click on it (or use the left / right arrow keys to select it).
