Firefox 4 cannot create new windows properly when using multiple monitors on OS X
I have had bad problems with Firefox 4 on OS X and doing anything involving new window generation, whether it's viewing Downloads, Page Source, or just a new browser window. I've finally diagnosed exactly when things break down, and that is when I'm using a second monitor plugged into my MacBook Pro, and have the menu set to be on the second monitor instead of the laptop screen.

I Found This Workaround
- Move the frontmost window of firefox to the main monitor (the one with the apple title bar).
- Do whatever it is you would do to spawn the new window.
- After the window has spawned, return your windows to the desired arrangement.
- Wait for the firefox team to post an update that fixes this problem because it is severely annoying.
The problem is persisting through version 6.0.2 (on an new iMac 21.5" w/ OS 10.7.1). (That workaround seems to still work, too.)
This has been fixed in Firefox 9:
