Are you one of those people that likes to tweak around with what is behind the pretty Firefox curtain? If you want to jerk back the interface and get to the guts of the browser, you might need to jump here or jump there to get to the settings you need.
One person made this job a little easier with the Edit Config Files extension for Firefox. Once installed it gives you quick and easy access to such things as the about:config screen and your UserChrome.css file as well. Here is a full list of the options from the extension.
UserChrome.css, UserContent.css, prefs.js, user.js, Open Profile Folder, and about:config. Quick and easy access to all the tweakers’ tools. Now I wouldn’t suggest messing around with these unless you know what your doing – but if you do this extensions can be a real time saver because you no longer have to go on a hunt for how to open each of these options up.
A few weeks back I got an E-mail from a guy who wanted to know if there was an easy way to customize the toolbar background for Firefox. You know, a simple way for people who just want to do a little personalization – not write an entire theme. Well, even though it is in an early beta I have found a project that will do that and a little more. Personas for Firefox is one of the more interesting Firefox projects I have seen for while.
