On various pages that contain a form with a sbumit button, nothing happens when I press the button. I get this error in the browser console:

TypeError: shouldLog is not a function[Learn More]

This started to happen today. Using 49.0a2 (2016-07-18).

At the moment, I can fill in this form because I've signed in with Chrome.

Does this happen on a clean profile? e10s on or off make a difference?

(also, can you link to a concrete testcase so it's easier for others to try to reproduce the problem?)

e.g. http://jsbin.com/qoducavamu/edit?html,output does not reproduce this problem for me on today's devedition build.

If you open resource://gre/modules/Console.jsm and search for 'shouldLog', do you see a function shouldLog() entry? Because I do (on OS X devedition from the 19th). So the errors don't really make sense unless your copy of devedition got corrupted or some add-on is messing with things.

Problem no longer reproducible after todays DevEdition update. 

The problem could still happen I guess. Clearly, wherever the shouldLog function is defined, there's some race condition where it relies on this to be in the scope but it's not.

Wow! The shouldLog function is defined in the very same file.

Well, yes, so "not in scope" doesn't make any sense. It should always be in scope. I don't understand why it would ever not be available. If you download yesterday's devedition separately, does the problem reoccur? :-\

How do I download yesterdays devedition?

That did not work. Downloading yesterdays build and running it did work, but the problem is no longer reproducible :(

Going to resolve INCO because without being able to reproduce it seems impossible to track down what's causing this. If it happens again we can investigate further.
