First tutorial in Firefox Add-on SDK "Getting Started" guide fails

[Mark Ballard]

The Mozilla "Getting Started" guide to Firefox Add-ons:

https://developer.mozilla.org/en-US/Add-ons/SDK/Tutorials/Getting_started

It doesn't work.

It is the page you go to if you are a nobby user making your first
brave steps to modify your Linux environment so you can work more
productively. You have been plucking up your courage and waiting for a
space in your busy diary. This is a big deal. It's daunting. But this
was the Linux promise: power users given unimaginable power. The geeky
brags you heard about Linux being better than Windows have echoed in
your mind down the years. And Mozilla makes it look *so possible* for
nobby users to get stuck in. Its tutorial is even written in something
close to plain English. Yes, you still believe in Linux! Even after
all these years of incessant bugs - you still believe! It is still
possible! You go for it!

And your SDK prompt vomits up a horrible looking error, like the devil
himself had possessed your machine and was taunting you for being such
a feeble user with such vain hopes that you might just skip daintily
through the Mozilla programming guide. Ha ha! You wretched little
worm! Hear me now! Hear my words of gibber and you tell me then where
are your dreams of man-machine harmony!

Your composure would be tranquillizing, Geog, were it not for the fact
that I was directed to this list by the very "Add-on" pages offering
succour to feeble users:

https://developer.mozilla.org/en-US/Add-ons

But of course it's the wrong list! But of course it is! Of course! Ha
HA ha! Of course!

The "Mailing list" link in that page's footer points to

reference to dev-tech-plugins.
