As part of project Async, we have been working on refactoring Firefox’
Session Restore to ensure that it does not block the main thread. Part
of the work has been cleaning up the code and the data structures
involved in Session Restore both to give us some maneuverability and to
improve the chances of catching refactoring errors.

Unfortunately, a large number of add-ons seem to rely upon these
undocumented data structures. Some of their features might therefore
stop working. If you are the author of one such add-on, you should
monitor carefully bug 874381 and its blockers. If you realize that we
are about to break your add-on, please inform us asap, so that we can
work out a solution.

Cheers,
David
