Accessing mail.yahoo.com as I have for many years, recently many functions do not work in Yahoo mail with Windows 10. Cannot select a message, cannot reply or forward, cannot go back to messages clicking the "back" arrow, cannot select the settings button. Yahoo mail works correctly in Chrome however. How to fix?? This should sound familiar.... It's copied from a 2 year old thread on the FF boards. I cleared the cache and flushed all my cookies. I removed my recently added addon (Malware Bytes). Problem still there.
