Reproducible: Always Steps to Reproduce: 1. Open up more than one tab that isn't blank. 2. Minimize Firefox. 3. Right-click on the icon in the taskbar, and choose close. Actual Results: Firefox doesn't close, and clicking on the preview or alt+tabbing into firefox does nothing. Expected Results: It should ask if I want to save the tabs, exit without saving or to cancel. This has happened to me since 4.0b4, and continues to happen after installing 4.0b5.
Can still be closed by task manager, though if it is not killed via processes but by applications, it says that it is waiting for a response from the user. After a bit more playing around, If I close each individual tab via the taskabr preview after it has become unresponsive, I can bring up the final tab on screen. However, if I click on it all I get is a ding noise; meaning that it supposedly has the 'save, exit, cancel' window open.
