Tested with two 24" Dell screens as well as on the MacBook Pro with only the laptop screen. Incompatibility with a plugin is part of the problem, but FF shouldn't display errors off-screen. Reproducible: Always Steps to Reproduce: 1. Upgraded FF version 2. Apple-N to open a new window 3. Actual Results: Error window in the top corner of screen (see screenshot) Expected Results: Error window should have latched onto the existing browser windows, or appeared centre/top of screen.
