PSA: Legacy extensions disabled by default on Nightly
After lots of recent discussion, it is finally happening. The patch to flip the default setting to disallow legacy extensions is in autoland at the moment and, barring some snafu, should be in tomorrow's Nightly builds. This is a bit anti-climactic since a few other changes that have already landed that broke a bunch of existing extensions. Also this has been discussed in a few other threads but repeating here for folks that may have missed it: there is a preference that Nightly users can flip to re-enable loading of legacy extensions in the addons manager (of course this setting won't magically make extensions that rely on the sdk or any changed internal interfaces work). We will continue to honor this preference in Nightly builds and in unbranded builds, but when 57 (and later versions) go to beta and eventually to release, that preference will be ignored.
