It's possible to stack the alert messages up, which can cause Fx to crash

[BillyRayPreachersSon]

By pressing Cmd-Q multiple times, it's possible to stack the alert messages up. For example:

• Press Cmd-Q to get the alert
• Press Cmd-Q again
• Choose either option to cancel the second alert
• The first alert appears

It doesn't matter whether you choose OK then Cancel, or Cancel then OK… if you choose OK at any stage, Fx will quit after all alerts have been dismissed. If you choose Cancel for all alerts, it will remain open.

It's also possible to get one alert per window, as the alert seems to be modal to the window rather than the application. I think it should be application modal, like the save dialog, for example.

I've also managed to crash Fx on severl occasions by holding down Cmd-Q for a few seconds instead of pressing and then releasing - like most normal users ;-). This has caused different behaviour, which can be seen by opening multiple windows:

• Open two windows
• Hold Cmd-Q down for a few seconds in one of them
• Switch windows and look at the Window menu

I've seen several different things here:

• A few 'Quit Firefox' windows are listed, and lots with empty titles are shown
• No 'Quit Firefox' windows are listed, and lots with empty titles are shown

Either way, Fx has normally gone on to crash or won't respond to the clicks in the quit dialogs any more... I've always had to force quit.

I'm using Fx v6.0 on Snow Leopard 10.6.8

BTW - Great extension... It certainly works nicely if you don't try and break it, although I would like to see the dialog being application modal... perhaps even get a "hold down to quit" floating message like Chrome has?
