Unable to open new windows in firefox 7.0.1 for OSX even in safe mode.

more options

I recently upgraded to firefox 7.0.1 and noticed that I am unable to open a new window, view source, or any other action that would open a new window now. I can open new tabs just fine, its just new windows that dont work.

I've tried running firefox in safemode, and the issue occurs there as well.
