I just downloaded Firefox but my mouse is dead. And it seems you can only increase the font of a web page by first dragging the "zoom" button to the toolbar and then using it. Is there any way to increase the size with just a keyboard?

Win 7 Pro.


You can use Ctrl together with +, - and 0 to increase, decrease and reset site zoom.



  • Ctrl + + to zoom
  • Ctrl + - to zoom out
  • Ctrl + 0 to reset
