I cannot open/ send emails from my yahoo account on an acer Aspire V5-571-6647. I have tried turning the pop up blocker off on chrome, and nothing.
Have you tried using another browser? Have you tried using another computer to access your yahoo account? Have you scanned for viruss or malware? You didnt state if you recently installed any security updates for your O/S or browser.
We can only "guess" at what your issue is without any detailed information.
You could contact Yahoo for help or support.
why would make and model of a piece of hardware have anything to do with a web based application?
