I am a Windows Vista user. Mostly i use Firefox as my default browser at home but need to work on Internet Explorer at office. From last few days, something is gone wrong with IE8 on my computer. I keep getting an error or pop up message saying, "Add-ons are disabled." Whereas i can see that add-ons are working. I am not able to disable those annoying pop ups. Could you guys please help me out of this ?
