For the past''' two''' days I can't log in to Yahoo mail with Firefox but it works fine on chromium.. The error is: ''Something went wrong We could not sign you in. Try again from a different device. Go to Help [or] Close '' I'm using a desktop and FF esr. I tried a VPN extension and it did nothing.. My FF preferences have always been to delete all info. on closing so I have no cache/cookies to clear. Tried with adding yahoo to cookie exception AND without any exceptions. Is this strictly esr? I never had this issue until this week. I had to use chromium to log in to my email to retrieve the code required to log in to THIS website. Is anyone else having this issue with FF??? Thank you.
