[Resending to get the correct Firefox list]
Now that we don't have legacy add-ons outside of our control, I would
like to propose that we stop using Object.freeze/Object.seal on most of
our objects.
I believe that this was originally done to provide some extra
security/stability relating to add-ons, i.e. stop them messing with our
internal interfaces. Now that this isn't a problem, it seems that we
should reconsider this.
One of the main reasons for opening this up would be to allow easier
stubbing for unit/integration tests. For example, using sinon with
stubbing makes it easier to work with - you don't have to cover multiple
components for a "simple" test if you don't want to. Unfortunately, the
current practice for using Object.freeze/Object.seal prevents this.
Are there any concerns or objections to changing this practice?
Mark.
