I've already develop a little Firefox Extension using XUL and i would like to re-write it better using the new Firefox Add-On SDK.
Looking on web (and in Mozilla Dev Center) i havent found a guide/tutorial that explain from a starting point to the end. All guides describe some component in a standalone way, there are not full examples from the First line of code, to the end.
Adding on this, each "tutorial" in Mozilla Dev Center have some warning that say "this tutorial is deprecated" and so on.
So, there is a clean starting point to lear Firefox Add-On using SDK ?
For toolbars specifically, there is a toolbar API example provided with the Addon SDK source on github.
