If you happen to use the Mozilla Firefox web browser, here are a few little hidden things about it you may not have heard about.
The Book of Mozilla
This has been in every Netscape browser and in every Firefox browser. In the address bar, type about:mozilla and you will read a strange passage from the "book" of Mozilla. No such book exists obviously but they call it as such. You can read up on what these mysterious words mean here.
Running Firefox inside Firefox
Type chrome://browser/content/browser.xul inside the address bar and it will launch another instance of Firefox inside Firefox.
Robots welcome you
Tying about:robots in the address bar makes this show up:
View the credits
Typing about:credits will give you a list of everyone involved in the development of the browser in one way or another. The list is long.
Nice, loved the robots bit.
The Book of Mozilla is cool too. Gotta love opensource programmers. I once found a reference to Spiderman in one program’s code.
Bonus: Hit the “try again” button on the robots page.
More bonuses: Favicon changes to a robot, title bar reads “Gort! Klaatu barada nikto!”
