Question

I tried to install mozilla firefox add ons and a drag and drop software from yahoo photos but my mozilla browser is not allowing to install softwares (add ons and extensions ) even after adding the respective websites into the allowed list. Can anyone help me in solving this problem???

Answer 1

turn off your virus checker, adware blocker and or spyware blocker, one of them thinks that the plug in your trying to install is malicious software
