I am running "nightly" builds for various reasons. The version that I fetch is from https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/ wherein we see :

https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/firefox-42.0a1.en-US.linux-x86_64.txt

This reports :

20150706030206 https://hg.mozilla.org/mozilla-central/rev/cef11c3e86c3

There is no precise build or version data that I can see inside the about:config panel other than perhaps extensions.lastPlatformVersion which reports "42.0a1" however this is not correct. The actual version that I have at the moment is from git repo https://hg.mozilla.org/mozilla-central/rev/cef11c3e86c3 at changeset 251448. I don't see a way to fetch this data from about:config nor via javascript. Is this data available?

hi, you can get this data in firefox from about:buildconfig (enter it into the address bar like you'd do with about:config)
