Firefox version 43.0.1 I have noticed since last two weeks on some website Popup window appears. Today Firefox had also blocked a Popup window but after that did not stop.

My computer OS, Drivers, Software, Adobe flash, Java also Windows Vista is update. I have also read Troubleshoot Firefox issues caused by malware and non of the solution apply to me. Malwarebytes and Norton is also updated and running.

I wonder why this thing started any help will be appreciated. Regarding my popup settings refer screen shot.

Thank you

Hi, Thank you for quick reply. I have already mentioned in my question " I have also read Troubleshoot Firefox issues caused by malware and non of the solution apply to me. Malwarebytes and Norton is also updated and running. " Regarding Adblock those are already running.
