The comma in the end is not only redundant, it actually breaks the code. 

Please check if the code works before submitting it for review -- the reviewers
might not always do it and unfortunately we have no CI (yet!) to catch these
things.

+THUNDERBIRD_URL = 'https://product-details.mozilla.org/1.0/thunderbird_versions.json',

[Vasily Kuznetsov, 2016/08/29 17:27:52]

This line is too long according to our guidelines (same as PEP8, max 79 chars).

The fix would be to do something like:

THUNDERBIRD_URL = ('......'
                   '.......')

Since this is pretty ugly, you might choose to hack your way out by doing
something like this:

MOZILLA_BASE = 'https://product-details.mozilla.org/1.0/'
FIREFOX_URL = MOZILLA_BASE + 'firefox_versions.json'
THUNDERBIRD_URL = MOZILLA_BASE + 'thunderbird_versions.json'

+SEAMONKEY_URL = 'http://www.seamonkey-project.org/seamonkey_versions.json'
