X-notifier for Firefox, Chrome, and Safari (deprecated)

As of the last 2-3 days, something changed with Yahoo for me which completely messed up my X-Notifier which was working perfectly.  I have 5 different accounts and it makes me log out of one before I can see another.  Even if I click the account in the X-notifier list, it will show me only the email address I currently have open. 

The XN version I think I have is 4.2.19 and my brower is Firefox with the latest update.

X-notifier checks as it should every 10 minutes but does not recognize or automatically open any other email account even though I have 4 of them  set to do that automatically in setup when a new email arrives in the inbox as well.  X-N will properly count the number of unread emails in the one account that I'm logged into but will totally ignore the others even though there are unread emails in those accounts.  I even did a Restore back to when things in XN were working perfectly and it still gives me the same results.

 Yahoo is always dicking with things and attempting to override or disable ad blockers so is anyone else experiencing this ?  I rely almost exclusively on XN and it's one of the only apps I have ever donated to.

I think I have what are referred to as new Gmail accounts. XN does not log in, but after manual login, don't log out, preserve cookies, it's fine, everything works perfect AFAICT. Could you please elaborate what GMailX is for?

on my laptop Xnoltifier works, but my desktop does not launch xnotifier and i must log into each account.  both are windows 10, both are updated Mozilla & Chrome, both are 64bit.

any ideas why?

X-notifier 4.2.19  > Mozilla Firefox 78.0.2  (x64) > Gmail not working

Suddenly X-Notifier stopped providing notifications for GMail. There are always zero notifications although I am still logged in all the Gmail accounts and clicking the icon of mail in X-Notifier drop-down opens proper Gmail account.

Cant check any of my gmail accounts with xnotifier on. Disabled xnotifer addon and google kept me logged in after relogging into all my google accounts. Enabled xnotifier and it wont check my emails anymore plus it logs me out of google. This just started happening recently so maybe there is a change on gmails end? I dont know.

Update: I reinstalled the plugin and relogged into my accounts and it seems to be working again.

Just wanted to let you know I am having issues with

X-Notifier not wanting to work with Microsoft Edge Chromium

and Mozilla Firefox .. I have deleted cookies, cache, made a new

Firefox profile deleted X-Notifier and reinstalled it again still 

no improving ..I have 4 Hotmail /Outlook email accounts only

3 will work while the 4th one does not want to work any help 

will be appreciated.  Thank you

Facebook is rolling out a new interface.
XN not checking FB account.

Firefox 76.01, X-notifier 4.2.19

I have 5 gmail accounts, all setup on X-Notifier, but regardless of which one I pick, it always logs me into the gmail at the top of the list. 

It wasn't always like this, so am I doing something wrong or is this a limitation in the current function of  X-Notifier and/or Firefox?

Hello,

I do receive email notifications on both accounts, but when I want to view emails, I stay permanently connected on the same account...

Thanks
