I have Dell desktop with windows 11. I could not access to yahoo homepage as well as yahoo mail after the system was updated. The message said check the proxy, the firewall as well as URL because the web site not secured. I did not have any problem before. Also another message said yahoo.com took too long to reach. But I used the old laptop with windows 8, I access yahoo homepage as well as yahoo mail are OK. I think the new security features of Chrome and Microsoft Edge are not compatible with yahoo.com. Please advice. Thanks.
