X-notifier 3.x for Firefox (deprecated)

I have  3 Yahoo emails, they were all working fine until a week or 2 ago and now one of them is constantly "not checked". The password and id is correct, but it ill not automatically check it as it does the other two. I have deleted and re added it, put @yahoo.com and without. Nothing has yielded success. Anyone have any suggestions. thanks

Recently set up 2 step verification for my Live account. At first X-Notifier worked fine. Didn't even pop up asking for a code. But just a bit ago it popped up asking for a code. Microsoft doesn't seem to realize it needs to send a code, because nothing gets sent to me. I cancel it, go to the page, do the code input myself, and I can check my email. But any time X-Notifier tries to check it, that box pops back up and no code is sent to me. Any ideas on how to fix this issue?

My new college email is @collegename.edu but managed by google. So the interface is all gmail, just reskined for the school. How would I add an email like this to my x-notifier list?

I've used this addon for years w/out a problem. Yesterday & today X Notifier disappears. It is not on my addon list. I go & reinstall X Notiifer then I click the options button and everything is already set up to my specifications. Why is XN disappearing? I have not made any changes to my computer, using Firefox 33.1 & XN 3.5.1

X-Notifier 3.5.1 Firefox addon: Outlook do not work; the account is grayed

Scripts been working since last update, but seems mozilla ff like to break things with 33.0.2, and now ff 28 back level quit working,.  Can xnotifier scripts be fixed i have had problems with google and yahoo scripts consistently .. Thank you..

Once again the y7mail.com account is not able to be accessed by x-notifier.

The account is a yahoo account from when they teamed with Channel 7 TV in Australia and branded themselves as Yahoo!7

the address is @y7mail.com and the login page is at the Australian site au.yahoo.com

It appears Yahoo have updated the login process for y7mail to include suggestions that we change our password there and then and for our phone number and this has stopped the notifier working maybe.

The login for my standard yahoo.com.au account is fine.

I just updated to the latest version but the problem still exists. The only account I can get into is my primary account

I get this error in SeaMonkey console:

I found that the enable button was The issue

I still can not log in or reset from the desktop....
