One side effect of this change is that if you're using third-party Gmail extensions, they're likely to stop working. We've contacted a number of the developers behind some popular extensions and provided them with an opportunity to create fixes, so check back with them for updates. We're sorry that it may be a bit of a inconvenience, but we're trying to make this change as smooth as possible.
