How I Created My Very First Firefox Extension
Too Long; Didn't Read
I had no clue about writing a Firefox extension, as this was the first time I did write one. My first step was to follow the tutorial. It explains the basics of an extension structure. Then, I followed the second tutorial. It explains how to create a pop-up menu for the extension but not how to interact with the web page. At this point, I decided to learn by doing, a technique that works well for me.
