Firefox may not be the most popular browser these days, but it's still the most configurable—right down to the smallest little pixel. If hunting through about:config is too tiring, though, free add-on Configuration Mania adds a ton of options through an easy-to-browse panel.


Firefox has more hidden settings than you could count, but sometimes, you don't know what you're looking for until you know it's there. Configuration Mania makes customizing Firefox a lot simpler: install the add-on, open up its settings, and you'll be greeted with hundreds of new checkboxes and options. Some of the best include:

Disable or customize autocomplete in the address bar

Change how Firefox displays images and animated GIFs

Change the URL and behavior of new tabs

Customize how Firefox works with Windows 7's taskbar and jump lists

Adjust how aggressive Firefox's popup blocker is

Customize keyboard shortcuts and multi-touch gestures

...and a ton more.

Best of all: If you uninstall the add-on, your configurations stay in place, so you can install it, go crazy, and then disable or uninstall the add-on. You can, however, reset everything back to the default from Configuration Maina's main window. Check it out at the link below.
