If you just need one specific web page to be zoomed in or out, you can use a keyboard shortcut to do so. This will only apply to the web page in question, and you may need to re-zoom if you clear your browser's cookies:  Go to the web page for which you want to change the font size. Hold down Ctrl (Windows) or ⌘ Command (Mac). Zoom in by pressing the + key while holding down Ctrl or ⌘ Command. Zoom out by pressing the - key while holding down Ctrl or ⌘ Command.
