lost my delete on yahoo e mail????

Answer 1

This is likely a web browser issue.  You may need to adjust your settings to allow Yahoo cookies, disable add-ons like ad-blockers, update your web browser or switch to a different one.  Security programs such as firewalls, anti-virus, malware or spyware can also block Yahoo sites and features and you will need to adjust their settings to allow Yahoo or to recognize Yahoo as a safe site.
