The documentation for writing add-ons is really bad. I challenge anyone to locate a one-page official documentation which walks you through a "hello world" add-on creation process? Right now there are a thousand pages talking about add-on, but each one of them also has a thousand links in it to make you jump to other places, then again to jump to more places. If someone with knowledge of the latest development can put a _complete_ walk-through for a basic "hello world" add-on in ___ONE___ page, it will be greatly appreciated. If there is a date stamp on the page (so readers know if it's still compatible with newer version of Firefox), that would be the greatest thing in the world. Had the documentation been better, I could have turned maybe a dozen ideas into add-ons which might be useful not just to myself but other users as well. More useful add-ons are definitely helpful to the Firefox movement. I am a strong believer of Mozilla's mission ("open web"), will continue to use Firefox exclusively for web browsing. Plus, Vimperator/Pentadactyl are indispensable. Writing more add-ons is another way for me to support the mission.
