firefox

Which shard is affected?
    Shard1
What happened?
    Sometimes when I switch from console tab to script tab or vice versa, the window start to lose control and flicks in between 2 tabs which I can't control.
What should have happened?
    This flickering should not happen.
How can we reproduce this?
    In a room, try to type some script in script window, then press save. Then go to console and enter some command, and press enter. The bug will sometime happen.

Thank you very much for helping out. Currently my work around is simply refresh the window, but, there might be solution, who knows...
