Yahoo Mail not check in FF or Chrome for 4.0.2

I've tried in two diferent browser, FF I usually use, and Chrome 52.0.2, the browser I usually use, and Chrome 57.0 with I never had use and needed to install and configure the extension. I can open the Yahoo Mail from the browsers (In Chrome never had opened the page and still open the page as logged direclty, without asking for password), but in both cases the extension put the yahoo mail in red and doesn't count the new mails.

I has not the two steps security on, and the Chrome browser has not more extensions installed.

I am having the same exact issue now for over a week. I think Yahoo must have changed something. Same issue on two different computers.
