I'm completely new to plugins for Firefox, and I don't know if it's
possible to write one in C#. I've written a quick BHO for IE, and I'd
like to do the equivalent for Firefox, but I'd really prefer it be in
C#. If I have to do in C++ I can, it will just take me a lot longer.

So, is it even possible to write a Firefox plugin in C#?

If so, is it possible to capture page events in firefox (MSFT
equivalent BeforeNavigate2 or NavigateComplete or DocumentComplete)?

Also, does anyone know if plugins can be disabled or uninstalled (?
unregistered?) by a non-administrative user?

Thanks in advance for the help!

Chad

Hi,

You need to know the interface FF is expecting, if it use COM you can
do it.
You better check the docs of FF and maybe postback the requirements of
the plugin

Not COM.

NPAPI or XPCOM.

D'oh...Ok, that's what I had gather from sifting through the docs as
well. I was hoping I was missing something or that it was just
burried and I hadn't found it yet. :(

Thanks!

I don't think you can write a FF plugin in .NET.

You wlll need C++ and native.

Check:
