I found myself staring at the “about:blank” parameter for an IE installation today, and that got me thinking if it works in other browsers too. It did. I’m using Firefox, and that cleared the address bar to a blank. And then I figured the developers HAD to include some more address bar commands and started looking them up. Here’s what I found:
about: A simple prompt without any parameter will display the Mozilla “about” information. Since it’s accessible from the top menus as well, it’s not quite a hidden feature.
about:buildconfig Obviously, it will show the build platform configuration and parameters
about:cache Will display info and statistics regarding your disk’s cache, including the name of your cache’s directory and a list of the entries you can find there. By default, Firefox doesn’t allow you to view the cached webpages, so this can be an useful option.
about:config Oh look, many many info. Indeed, it’s the most complex and meaningful of them all. Careful on what you plan to change here, your browser won’t run properly after if you play with the wrong things.
about:plugins Of course, what is Firefox without it’s powerful extensions? This option will display detailed information about all the plugins installed for Mozilla Firefox.
about:credits It’s time to give the credit to whoever deserves it. There’s an alphabetically sorted list of all the people that gave their contribution to the development of Firefox.
about:Mozilla This is a weird thing. It will display the so-called “Book of Mozilla”. Something similar was present in Netscape too. There’s actually no real book although the quotations might give you that impression.
Have fun browsing through your browser’s internal features.

about:plugins is not about extensions (“Extensions are small add-ons that add new functionality to Firefox, from a simple toolbar button to a completely new feature. They allow you to customize Firefox to fit your own needs and preferences, while letting us keep Firefox itself light and lean.”), but it’s about, err, plugins (“Plugins help your browser perform specific functions like viewing special graphic formats or playing multimedia files. Plugins are slightly different from extensions, which modify or add to existing functionality.”).
Great find! Thanks for sharing!
Firefox has an extension that will allow you to choose any of these off the help menu
https://addons.mozilla.org/firefox/776/
Or…….you could always just install the MR Tech About:About extension for Frefox. This puts all those so-called “hidden” pages into a drop down menu off the Help menu.
