The secrets of the firefox. Have you ever seen it live, in its natural habitat? Now you can.

The most recent statistics seem to indicate that Firefox has reached a 15% market share in the browser battle. Now that may not seem like much, but considering the hold that IE had until the emergence of Firefox, it is quite amazing. The ability to customize the browser with add-ons has contributed greatly to its growth, but there is another customizable feature that far too many people are unaware of - about;config. Below you'll find some of the well known and not so well know tweaks/hacks that will improve your browsing experience

Type about:config in the address bar and press Enter, and you'll see all the settings currently enumerated in prefs.js, listed in alphabetical order. To narrow down the hundreds of configuration preferences to just the few you need, type a search term into the Filter: bar. (Click the Show All button or just clear the Filter: bar to get the full list back again.)

To edit a preference, double-click on the name and you'll be prompted for the new value. If you double-click on an entry that has a Boolean value, it'll just switch from true to false or vice versa; double-click again to revert to the original setting. Not all changes take effect immediately, so if you want to be absolutely certain a given change is in effect, be sure to close and reopen Firefox after making a change.
