User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-GB; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-GB; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6

I have an extension installed which (100% reliably) generates a "Warning: unresponsive script" at start-up.  That's fine (by me), but the dialog box containing the warning appears partially off-screen making it impossible to read (but possible to dismiss) without a workaround.  That workaround is simply to use OS X/Exposé's "Application windows" hot-key (usually F10) which centres the window.

At the point in start-up that the dialog appears there are no accompanying Firefox windows (I didn't just cut them out of the screenshot!).  I suspect this is relevant, and expect that the only way to trigger this bug is through an extension which involves scripts and which is really slow to load, and which blocks display of the main window (or perhaps triggers the hang detection quicker than Firefox restores the previous browsing session).

I don't recall whether I see this problem when there *is* a main window, but if you'd like to point me to a page engineered to trip the hung script detection then I'd be happy to try.

I'll attach a screenshot in a moment of the top-left of my screen with the dialog present.

Reproducible: Always

Steps to Reproduce:
1. Start Firefox with slow extension enabled.
2. Wait.
Actual Results:  
Dialog appears partially off-screen.

Expected Results:  
Dialog appears entirely on-screen.
I'm seeing this, too, using FF 3.6.x on an Intel MacBook Pro running 10.6.6, although for me, it's frequently completely off-screen and prevents graceful quitting of Firefox.
Thomas, is your issue like bug 596690?

zakwilcox, which add-on causes the dialog?
Lazarus does.  These days I'm running 3.6.13 and have stuff configured a bit differently (Lazarus to store much, much less form data, and FF to store much, much less history) and no longer get the dialog on start-up.  I'm not sure which change did away with the dialog at start-up (I can still force it at runtime easily, but it gets a frame and is placed on-screen as expected).
Wayne, I wouldn't say so.

For me, if I've got a long-running Firefox process, quitting often doesn't happen because of the modal "unresponsive script" warning, which might have been there for a while but doesn't show up on any windows. In order to get it to show up, I have to click and hold the Firefox icon in the Dock and then it appears, but I can't click it because of the way Mac's Exposé interface works.

I usually use the menu from the Dock icon to then quit Firefox, which it responds to (unlike Cmd-Q).
OS: Mac OS X → Windows 7
Oh, and to follow up on add-ons being related, I've seen this most frequently with Firebug.
