1096083 - [e10s] document.commandDispatcher.focusedWindow.scrollY is 0 and can't scroll

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Lajos Koszti]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141105223254

Steps to reproduce:

I am working on an extension, which scrolls the focused window.

If e10n enabled, I can't query the scrollY of the window and can't scroll it.

In browser console running the following code (and focusing the window) alerts the scrollY.

setTimeout(function () {
	alert('focused window scrollY: ' + document.commandDispatcher.focusedWindow.scrollY);
document.commandDispatcher.focusedWindow.scrollTo(0, 10);
}, 1000);




Actual results:

scrollY always returns 0 and can't scroll.


Expected results:

ScrollY returns the correct scrollY value and scrolling.

I meant e10s instead of e10n

I'm guessing you can't do this in e10s and have to use message-passing instead https://developer.mozilla.org/en-US/Add-ons/Working_with_multiprocess_Firefox , but I'm tagging this as tracking-e10s for someone in the know to comment.

Hi reporter,

Can you please provide a download link for your extension, so I can test this on my end?

Also, please try to reproduce this on the latest Nightly(46.0a1) and provide the results. When doing this, please try to reproduce with a new clean Firefox profile, maybe even in safe mode, as some of this issues may be caused by third party installed add-ons or custom settings(https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems).

Thanks,
Paul.
