I'm trying to create a Mozilla browser plugin for the sole purpose of detecting with javascript whether or not an application that I have written is installed. This was inspired by another stackoverflow question and answer on a similar subject.
All I want really is a HelloWorld type example as what I need to write will be even simpler than that. There is a lot of information on the Mozilla website, but as a plugin noob and a C++ novice I'm experiencing information overload. I just need a step by step "this is how to create your first simple plugin".
I have already written the IE equivalent by following this ATL tutorial. This is the kind of level of guide that I would ideally like to find.
Please note, this is specifically about Mozilla plugins and not extensions - Googling this subject brings up a lot of information about extensions in addition to plugins.
