Earlier today, we announced on the enterprise ML several changes to ESR.

First, as Dave Camp mentioned during the Firefox All Hands, we are
started some developments to improve
our support for enterprise users.
More information can be found on the wiki:

Second, we will branch ESR from 60 instead of 59.
This will give us more time to work on the Enterprise policies.
Also, In parallel, this means that we will have more time to delete
old/dead code before branching.
As a disguised advertisement, I am using this email to remind that
Marco Castelluccio's tool
https://marco-c.github.io/code-coverage-reports/ is your best friend
to find dead code [1].

Last but not least, we also warned our enterprise users that ESR52.9
(EOL August 28th) will be the last release supporting legacy add-ons.

The wiki and the ESR FAQ have been updated:


PS: Also, for people on these two MLs who are still using Windows XP,
you'll get a few more weeks to update ;)

The Firefox ESR (extended support release) is based on an official
release of Firefox desktop for use by organizations including schools,
universities, businesses and others who need extended support for mass
deployments. Since Firefox 10, ESR has grown in popularity and many
large organizations
rely on it to let their employees browse the Internet securely.

We want to make customization of Firefox deployments simpler for
system administrators and we’re pleased to announce that our next ESR
version, Firefox 60, will include a policy engine that increases
customization possibilities and integration into existing management

What is the policy engine?
The Policy Engine is a project to build a Firefox desktop
configuration and customization feature for enterprise users. The
policy engine will work with any tool that wants to set policies and
we intend to bring Windows Group Policy support soon. We’ll be
initially supporting a limited set of
policies but this will be evolving through user feedback.
More details on the policy engine can be found here.
Bug reference <https://bugzilla.mozilla.org/show_bug.cgi?id=1419102>

What’s the plan?
In order to accommodate the group policy implementation, we are making
Firefox 60 our next ESR version and will be following this plan:

  * May 8th - ESR 60.0 released (we’d love feedback from early
adopters at that point and will be sharing a feedback form through the
enterprise mailing list)
  * July 3rd - ESR 60.1 released
  * August 28th - End of life for ESR 52 and release of ESR 60.2.0. No
further updates will be offered for ESR52 and an update to ESR60.0.2
will be provided through the application update service

Also please keep in mind that Firefox 57, released last month,
supports only add-ons built with theWebExtensions API
<https://developer.mozilla.org/en-US/Add-ons/WebExtensions>. This
means that Firefox 52 ESR is the last release that will support legacy
add-ons.  If you developed an add-on that has
not been updated to the WebExtensions API, there is still time to do
available, and you can ask questions by emailing
dev-addons at mozilla.orgor joining the #webextensions channel
atirc.mozilla.org <http://irc.mozilla.org>.
If you are supporting users who use add-ons, now is a good time to
encourage them tocheck if their add-on works
Firefox 57+.
