XUL

Trying to get this extension stuff working, it is insanely complex at the moment.

Having to learn about all these do's and don'ts about what is possible/plausible or not and all the precautions to try and prevent conflicts with other extensions Dx

I will learn in the end, it's the same as learning a new programming language, even if parts are similar I need to throw out my current knowledge of Javascript and start again..

Even though it is annoying, once I get the hang of fit I suspect I will have some fun :D
