Do you know about:config? Enter it in Firefox’s location bar and you get instant access to its advanced preferences, a playground for customization fans, as it allows to tweak a larger number of features. Unfortunately, it is not very informative (and it is not designed or supposed to be), so it usually takes some help (like Mozilla Links’) to get to the preferences and set it to valid values you need.

Configuration Mania, developed by Popoki Tom, removes that limitations adding user interface to that large amount of advanced preferences. Once installed, some gems are easily uncovered like an option to set the Alt key as a modifier for the mouse wheel for faster, page size, scrolling. Or define the tab key behavior (all elements or links only). You can get more ideas from Popoki’s suggestions.

I would prefer it integrated within the Options window instead of as an additional item in the Tools menu, if not as additional pages (which of course would make it even more cluttered) at least as a button in the Advanced section. Aside from some typos and the missing icons, users will welcome this enhancement.
