Christoph, what's going wrong here?

It's missing one of the securityFlags needed to call asyncOpen2() on it. In fact we should use |loadUsingSystemPrincipal = true| for that load, similar to the other callsite within browser/devtools. See  which is the other callsite within browser/devtools which we converted at the same time within the same bug. That conversion btw landed in FF41, so this feature has been broken for a long time. I suppose we should uplift to all channels?  https://hg.mozilla.org/mozilla-central/rev/eccbddbe4761#l3.19

I suppose we should uplift to all channels? I mean, not sure it meets ESR criteria, or ones for release. But definitely aurora+beta. Rest is up to you.

Comment on attachment 8783965 [details] [diff] [review] bug_1297370_update_snapshot.patch Approval Request Comment Importing *.json into the canvas debugger fails without this patch. The Bug that regressed that landed in FF41, so this feature has been broken for quite some time. [Feature/regressing bug #]: Bug 1167053 - Convert NetUtil.newChannel2 callsites to use new API - update newChannel2 [User impact if declined]: See approval request. [Describe test coverage new/current, TreeHerder]: Tested manually using the description in comment 0. [Risks and why]: Low, because it only provides the necessary default when loading a local file into the debugger. [String/UUID change made/needed]: no
Pushed by firstname.lastname@example.org: https://hg.mozilla.org/integration/mozilla-inbound/rev/dab0693cae68 Provide security flag for channel within snapshotlist. r=gijs
Wes, just want to make sure this lands today in m-c so I will have time to uplift to beta for tomorrow.
Comment on attachment 8783965 [details] [diff] [review] bug_1297370_update_snapshot.patch We want developers to be able to import json, let's uplift to beta. Verified in nightly and the risk seems limited to this feature.
