.net - How to write FireFox extension with Visual Studio using C# programming language?

Question

I was wondering if it's possible to write Firefox extension using .Net Framework? Had anybody such experience in writing Firefox extensions using C# programming language? Any good sites or guidelines would be very helpful.

Here is an example of what I need. Extension to enter phone number and to send SMS Message. I draw it in Paint, so I'm sorry for having no artistic touch.

Answer 1

Assuming you're asking about writing an extension (and not a plugin), the best place to get started is with the info at the Mozilla Dev Center.

Konamiman is correct: extensions are mostly XUL (an XML grammar) and Javascript, packaged into a ZIP file with the extension .xpi. The various links from the page I linked should answer basic questions, like the one you posted above:
