Comment 2 for bug 803831

Thanks for reporting this and helping in making Ubuntu better.

I have reassigned the report to Unity, as it seems more a Unity problem than a Firefox problem. When you say "and when the window is unmaximized and on the left side of the monitor." are you keeping the Firefox window large enough to cover all the Unity launcher? I ask this because I had a similar issue and the Unity launcher was actually unhiding but behind the Firefox window and I could not see it.
