Following up on the message quoted below (Intent to ship on pre-release
channels), we are now planning to ship support for CSS writing-mode,
text-orientation, and related logical-direction properties (things like
block-size and inline-size, margin-block-start, etc) enabled by default
on all channels.
The RELEASE_BUILD condition that has been keeping these features
disabled for release builds was removed in bug 1138384, which landed for
Gecko 41. So unless we have reason to revert this during the Aurora/Beta
period, we expect these features to ship in Firefox 41.
Relevant specifications:

We are aiming to enable support for CSS writing-mode and related
features (i.e. vertical text support) in Gecko 39.[2]
This will be enabled behind an #ifndef RELEASE_BUILD condition, so that
for the time being, these features will be available by default in
developer builds, but not in the release version.
Once more key parts of CSS layout have been adapted to support vertical
mode, we'll remove the condition and enable writing-mode by default on
release as well as dev channels.[3]
cc'ing firefox-dev and dev-gaia lists, particularly to make people aware
that while we encourage experimentation with the new properties (please
test and file bugs!), you should not attempt to use them in front-end
code that will ship to release channels where writing-mode remains
disabled-by-default for now.
