[Updated 11/27/2017 ...correctly, I hope. (Scroll to bottom for notes on XN 4.1.7, Chrome, Safari)]
First... Note that X-Notifier 3.x will only work with Firefox up to version 56...
(and then perhaps for another year with the Extended Service Release (ESR) of FF 52.5.0.
See: https://www.mozilla.org/en-US/firefox/organizations).
Mozilla has said that they will [block the installation of legacy] addons beginning with FF 57. Until then...
Yahoo / Att
If your Yahoo email account is attached to Att.com you can't use imap with XN anymore.
They have removed the option for giving access to less secure apps with yahoo/att accounts.
I had an yahoo/att account setup for imap and it worked untill last week.
This link https://login.yahoo.com/account/security#other-apps
will only let you change your password with yahoo/att accounts.
Regular Yahoo accounts work perfectly with the imap instructions above.
Gmail wants notifacation
Gmail wants varification code after the new script was loaded but I do not have any and never had any bedore
??
Works fine for me. Don't know what to tell you, except update to X-Notifier 4.1 (which only fixes Yahoo) and then try Gmail. If it doesn't work... try the modified Gmail script, again.
Stupid google thought I was
Stupid google thought I was not who I said I was so had to jump through hoops but it works now, sorry about that.
Hello, how do you solve this?
Hello, how do you solve this? My gmail also kept asking verification code but I don't have one or never made one. However I did activate 2-steps-authentication.
Google support
Perhaps you could try this...

Hotmail
Is it possible to make a script for Hotmail to use with 3.x? After stupid beta switch, hotmail greyed out. I am really greatful for being able to use again gmail with 3.x, thank you!
"deprecated"
Version 3.x has been labeled "deprecated"...
...as it is soon to cease to function on newer versions of FF (57+), supposedly.
Perhaps someone could strip the hotmail script out of version 4.x and may have to rework it for 3.x and then make it available separately to load into 3.x.
