Facebook and Firefox does not recognise Firefox as my browser.Unable to install any add-ons from Firefox.
This all happened suddenly by itself. I did not install any new programs or software of any kind. I have Norton security software, but this has been installed on my PC for 6 months without any problems. I have uninstalled Firefox3.6,10. And reinstalled it, but it does not solve the problems.
