When I try and log into BT Mail it comes back with invalid password. The password is saved. This only started happening today (22/5/2020) - its been working perfectly up to now. I did not want to change my password and experimented with my other access methods - IOS on my Ipad and Iphone works perfectly, likewise if I entered via Safari works fine only Firefox comes back with the block - what has changed. I have tried entering the password manually and cleared all cache but still no joy ? //Andy
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.
