Yahoo account greyed out

Hello,

 

I am using xNotifier version 3.5.23 and all other scripts (gmail/hotmail) are fine after updating (http://xnotifier.tobwithu.com/dp/comment/12110#comment-12110) but yahoo is greyed and not working properly. Firefox version: 53.0.3(32bit)

Is there any way to solve this issue?

Thanks!

There is a problem with yahoo checking as of today. Some emails checked, but most not checked.

As of today this is not checking and opening Yahoo Mail though if I click on the greyed bit I am taken to Yahoo login page.

If anyone has a workaround please explain in basic terms thanks!

(My yahoo acct continues to work for the time being.)

I've been using 15 yahoo emails with x-notifier for a long time and 5 of them continue to work well, but others are now greyed out. All of the accounts were set equally (interface, etc.). So obviously that's not the reason.

I've been using 3 yahoo mails. I noticed my main one was taking a while to check/load this past week or so and now none of them work. I still think it is something to do with yahoo as I have noticed some changes recently. .

If one doesn't double check the obvious...
...well, popsy and rsherb76 are more likely to fix their yahoo problems, as they've both noticed changes in yahoo.  Just sayin'...
I await yahoo's new rollout.

And finally all of the accounts are greyed out.

upd: just turned one email to classic, not affected to x-notifier

It may be possible to use an application password (by turning on 2-step authentication and using 'generate app password'), or... go to account settings and 'turn on less secure sign-in' (for old apps)... see:

I use a couple other mail apps and the less secure sign-in... although there is a constant post-login nag screen to turn it off. I also allow Chrome to save the login.
