Those hello world examples, while not great, usually work. [Did you make sure you zipped correctly?](http://stackoverflow.com/a/23690580/484441)? What have you tried? What is the specific error? – nmaier Jun 26 '14 at 09:47

The error message is: "This add-on couldn't be installed because it appears to be corrupt." – user3377708 Jun 26 '14 at 10:42

Yeah, that sound very much like incorrect zipping (see my previous link). Otherwise you'll need to post your actual code if you want help figuring out what is wrong. – nmaier Jun 26 '14 at 10:45

1Thanks a lot. The problem was in the provided link at the following point: "Quite often people actually zip up the outer folder. I.e. the resulting zip (.xpi) then contains /some-addon-folder/install.rdf instead of just /install.rdf. Make sure to not zip the outer folder, just the files and subfolders within.". Please make it answer. – user3377708 Jun 26 '14 at 10:52

I have a bunch of templates on my gist site. What are you trying to make an addon of? read the part explaining my gist naming scheme at noitidart.github.io and then go my gist pages – Noitidart Jun 26 '14 at 21:21

Alright, as we figured out together, the XPI file was incorrectly zipped.
It did not include the XPI items directly as it should have, but within a subfolder in the zip.
Correct zipping of XPI files is further discussed here.
