Topic: How to create XUL extensions?
I have been trying for months to re-write my WebExtensions addon so that it will work on Iceweasel-UXP. It's got just one javascript file, about 20 lines of code that hides some text on the pages of a certain web domain. It has no UI components.
I have not been able to find a comprehensive XUL extension introduction. I've tried to learn by example from some iceweasel-uxp extensions, but they are either way more complicated than my extension or are bootstrapped (mine isn't). Mozilla MDN has deleted many of its XUL pages. Most of th XUL tutorials online are about writing full applications.
I've packaged and loaded my extension in the browser. The browser gives no error messages or warnings. I've validated my javascript. All I need to know is how to get the browser to run my extension. The code is just completely ignored.
