User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160107004004

Steps to reproduce:

FIREFOX DEVELOPER EDITION 45.0a2 (2016-01-07)

1) Open YouTube or any website with social sharing buttons.
2) Click the Share to Facebook button.


Actual results:

Page opens, BUT, it has a displacement "feature". The pop-up windows, moves from left to right on the screen.
In some sites that the share option just opens a new tab and not a new window, FF resizes and beings moving from left to right.


Expected results:

The windows should NOT move by itself.

Have you tried if you see this issue in a new profile, too? You can find details on how to create a new profile (without changing anything in your regular profile!) at https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles .

Have you tried if you see this issue in Firefox's safe mode, too? You can restart Firefox into safe mode by using the 'Restart Firefox with add-ons disabled' entry in the 'Help' menu. This will also disable graphics hardware acceleration and some JS engine optimizations, not just extensions and plugins. See https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode .
