Taken shamelessly from the excellent Lifehacker-blog: The Zoom Textarea user script lets you enlarge textareas on any web page for more glorious room to type – so handy for writing forum posts, weblog comments or posts, and web-based email. The Zoom Textarea user script requires the Firefox Greasemonkey extension (at least version 0.3.) If you’re a Firefox user without Greasemonkey, here’s how to install the script: # In Firefox, click “Install Greasemonkey” from here. Be sure to allow “greasemonkey.mozdev.org” to install software in your browser. # Restart Firefox. # Right click on this link: zoomtextarea.user.js. # Click “Install User Script.” Press OK. # Refresh any page with a text area on it, and you will see a zoom in and zoom out button above it. If you spend a good part of your day typing into web pages, Zoom Textarea will quickly become indispensable for your writable web.
