Just a heads up, a few of us have run into problems with extensions
breaking in nightly. The problem is probably not restricted to extensions.
The scoping rules for const in JavaScript have changed to conform w/ the
ES6 spec [1]. My understanding is that a const variable is now
restricted to the scope it was declared in.
Basically the following no longer works:
if (foo) {
const bar = ...;
}
bar.baz();
This broke lightbeam [2], mozmill 1.5 (I believe it's fixed in the 2.0
branch) which AWSY uses, and probably plenty of other things that have
been using const since, I'm not sure when it showed up, but at least the
past 4 years.
So if you're seeing failures since around 11/5 this could be it, you
just need to rework the scope of your const statements (and maybe not
use const unfortunately).
