Is your Issue reproduceable Extension-less in Safe-Mode and/or using a new Profile?

I do not get the message box when I start it in safe mode but I still get it when I disabled all my extensions and open firefox normally.

I have just installed RC1 and encountered the same problem.

Please note I am running Windows 7 64bit which is a new clean installation - (i.e. had to re-install Windows). Firefox RC1 was installed over 3.6.15
