Hi,
Firefox 37 was supposed to be released on 2015-04-07 but has been moved up one week, to 2015-03-31 [1], to not coincide with Easter. I suppose the same goes for the 31.6.0esr release (why shouldn't it?). If that's so, will you also move up the release date for the next Tor Browser for a same day release with the corresponding Firefox ESR release?
The same apparently goes for Firefox 38 (moved up one week) but Firefox 39 will be on schedule (so there will be *seven* weeks between 38 and 39). I guess that in general I'm interested to know if you'll always aim to follow Mozilla's release schedule. This is quite relevant for us Tails developers to know, so we can adapt our release cycle according to your (and indirectly, Mozilla's) release dates.
Cheers!
