User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20120424 Firefox/14.0a1
Build ID: 20120424075151

Steps to reproduce:

Using Nightly 14.0a1 (2012-04-24)

Using Dual monitor configuration. Primary display 1920x1080, second display 1280x1024 on the left of the primary.

Two Firefox windows open maximized on both displays.

Middle click to scroll on the far left hand edge of the second display.

Error state only appears when the cursor is within half the diameter of the scrolling icon of the left hand screen edge.


Actual results:

Circular scrolling "icon" appears on the far left hand edge of the primary display.


Expected results:

Scrolling icon should have appeared on the far left hand edge of the secondary display.

Additionally clicking similarly near the left hand edge of primary display puts the icon incorrectly on the far right hand edge of the secondary display.

Hello Jonathan,

I have just found your old report and want to ask you if this is still a problem?
I have tested it on my site, but i can't reproduce it.

thank you for the help and sorry for the late response from our site.

As of Firefox 32.0 the first part of this bug is resolved.

However the second part of this bug is still existing.

That is that when middle clicking on very close to the left-hand edge of a browser window to scroll, the scroll icon appears on the right-hand edge of the next monitor instead of appearing touching the left-hand edge of the screen as it does with single monitor configurations
