Everytime I launch Firefox, Windows keeps asking me if I wish to set it as my new default browser. Googling it shows that this is a problem reported by other users here and here but there is no solution. This doesn't happen on any system without VMWare guest tools installed. Fusion version is 6.0.2 and Host OS is Mavericks (10.9.2).
VMWare Preferences => Default Application > Both mail and web pages are unchecked.
Any solutions?
