How to make firefox or google Chrome Add-on?

Question

I Want to make Firefox and Google Chrome Add-on in which language can i make?and how to make it in Firefox or Chrome compatible?

Answer 1

For Firefox the language is mostly JavaScript and XUL (XML UI Language). Although it is possible to use Python and XUL, or even have compiled code bound trough XPCOM/XPconnect. But that's definitely not for beginners.

For Chrome the language is actually JavaScript, HTML and CSS. It's very similar to developing web application.
