A Firefox extension for the textboards

I wanna make a Firefox extension for the text-boards, ut I don't know any languages in programming or much about computers at all. Can anybody walk me through how to make an extension on Firefox; simple but tight (should have all the features the image-board one has)?

Fuck off. I'm not reading any bullshit on my own, cocksucker. My request was for somebody to walk me through how to do it. Not to cough up worthless, unreadable textbooks. Can you help me? There's plenty of other people on this site that will if you won't. Cocky asshole.
