[Tracking Requested - why for this release]: Regression in 45, in a feature (FxA) that we really do not want to look bad.

The most obvious suspect in the linked pushlog is: "Bug 1218022 - switch to fx_desktop_v2 context for Firefox Accounts." I was able to reproduce on my Mac using current DevEdition.
> I was able to reproduce on my Mac using current DevEdition. And I can do so by signing out and singing back in rather than having to start from a fresh profile.
Possible related to and/or fixed by the changes to fxa_desktop_v2 here? https://github.com/mozilla/fxa-content-server/pull/3442
Yes, looks like a dupe of https://github.com/mozilla/fxa-content-server/issues/3353 which should be fixed with next FxA server deployment.
Ryan, do you confirm that it is fixed? Tracking to make sure we address the issue if it is not actually fixed.

The fix is not in production yet, but should go live this week; leaving ni? myself to confirm when it's deployed
The fix for this is now live, so closing this out, please re-open if the error still occurs.
