incorrectly think they are using beta.
It is possible to deduce this information given just the version from
navigator.userAgent and the value of navigator.buildid. Unfortunately as
far as I know there is currently not an API to make this easy. Maybe
somebody from releng can correct me if I'm wrong: currently I mostly go
looking through the dated build directories: e.g. currently my buildid
is "20130504030913" so I go to
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2013/05/ and grep
for 2013-05-04-03-09-13 which shows me that this is a mozilla-entral build.
Unfortunately the beta/release builds are not in this directory, they
are separate so you have to use a different heuristic ;-)
i'm interested in either the value of app.update.channel, or the value
passed to configure via --enable-update-channel.
is this currently available to javascript? if so, how? if not, do
you think a request to expose it would be successful?
I do not think that we would want to expose this information to the web.
