    I believe it is either C or C++, but you can write extensions for Firefox using XML and JavaScript. For a great tutorial on doing this go to: http://www.rietta.com/firefox/Tutorial/overview.ht...

    Because odds are you won't want to touch the Firefox code base unless your a very expirenced programmer.

    C++, and different internet-appropriate programming launauges. (CSS, Javascript), they additionally use some in-dwelling house stepped forward XML-based markup languages (XUL and XBL) Many courses made at present are in lots of cases written or based of C and/or C++.
