Yahoo Mail is used by Basic Mail Only under SRWare Iron
I am using SRWare Iron version 74.0.3850.0 64-bit and I have noticed that Yahoo Mail (the Basic Version) works on this browser. SRWare Iron should be supported on the "New" version of Yahoo Mail. On top of that, I have submitted a letter that was on May 28, 2019 regarding this issue and this idea may fall deaf (may not be considered to be accepted) because: (1) the response to this issue/idea has a 98% chance of having someone that doesn't understand English very well to misinterpret this and (2) having a forum support doesn't hold up very well in regards to this particular issue. Sadly, I know I will be right in regards to the responses involving this and these ideas are "unsolicited" by any corporate measures. Especially if this is a multi-billion dollar corporation like Microsoft or Google.

I would like to use Yahoo mail with the Blynx (Lynx text browser, with blind friendly settings
