Mozilla’s Firefox is probably the most used and abused browser worldwide. Why? Because it’s the most customizable browser, allowing developers to create very useful plugins and extensions, that enhance the browser to a whole new level. What many Firefox users don’t know is that the browser has many of its settings hidden via its menu, but only accessible via the about:config command.
To take a peek at Firefox’s hidden gems, just type about:config in the address bar and voila, config extravaganza! Hundreds of configurable parameters are right under your mouse, but is it that simple for the not so trained eye?
