Hello azrdev, Are you still encountering this bug on the newest Firefox build 42.0 or Nightly build 45.0a1? I can not reproduce this bug. Thank you, Justin

@Justin: with 42, yes. Nightly I didn't test.

Alright, I still can not reproduce on Firefox 42. I will get this to a dev.

Yang: I'd like to add this to the One and Done tool to get a reproduction confirmation from a contributor. In order to do that I'd like to change the status to UNCONFIRMED again. I'll go ahead and do this on 02-29 unless I hear otherwise. Thanks!

I don't understand what you mean, I can reproduce the problem in the latest Nightly.

If you can reproduce this in the latest Nightly build than it doesn't need anything else.

Sorry, this is a dup of bug 1171746 and there is some lack of agreement on how to handle it.
