989828 - Mouse cursor sometimes disappears while using Firefox

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

I'm using Firefox Aurora on OS X and sometimes the mouse cursor will disappear. The mouse is still "there" in that when I move it around I get hover styles appearing on things and can still click on stuff. When I move the cursor outside the Firefox window I can see it, but when I move it back to the Firefox window it disappears again.

It's a long-standing issue, but I most often encounter this while watching something on air.mozilla.org and switching tabs around. So for a while I thought it was just something wonky with Flash and dealt with it. However I just ran into it again on normal non-flash tabs; I was navigating around some bugzilla pages and a zimbra tab and the cursor disappeared. I don't have concrete STR but wanted to file this anyway, and will update with more STR as I have them.

This issue seems to still occur even now with the Developer Edition 44.0a2 (2015-11-03). This issue seems to definitely be related to videos but not directly tied to flash since I don't have it installed. Currently I'm not able to consistently reproduce the issue. But I'll be keeping an eye out for this issue.

When the mouse pointer disappears, I can bring back the cursor when I command+tab to another application.
