I turned my computer on this morning, as per normal and without having any previous trouble, and I cannot use Firefox to open a window more than once, be that from my desktop or Rocketdock. For example if I have used Rocketdock to open Yahoo, which is setup to use Firefox by default, it will work. However, if I then attempt to use any other Firefox assigned icon or the icon on my desktop all I get is a brief flash of the hourglass and then nothing. I do not, however, have any problems opening up multiple tabs in that one open Firefox window. I have run Registry Booster, CCleaner etc and I have also re-installed Firefox but without any luck. Any ideas? Cheers.
