In the Zoom Options page, you can choose a different Zoom engine (CSS, Font-size, or browser engine). For what kind of scenario would you like to have a different Zoom engine? You can choose the font-size engine in the Zoom browser extension, and for the browse engine use the zoom button of the Firefox web browser.
