Comment 89 for bug 175904

To give some background on this issue, Firefox now supports startup notification:

The issue in this bug only occurs when there are multiple workspaces.

Removing this Firefox patch would be a regression in the single workspace case
because it would require clicking on a flashing browser entry in the task list
after activating an external link.

From IRC:

<owen> walters: metacity could look at the window role and alter the behavior
based on that
