X-Notifier on Firefox has stopped working... again

I'm running Win 10 with Firefox as my browser. Until two or three days ago, X-Notifier was working normally. It abruptly stopped working. I have enable and disabled it, removed it and reinstalled it – nothing doing. This has happened before, then X-Notifer just crept back in.

Any ideas why this has happened and what I can do to get it to work again? Thanks.


X-N is still working for me on latest FF.

Perhaps you might try disabling all your other FF add-ons and then restart FF and see if X-Notifier works.
If it does, then you might re-enable one add-on at a time and restart FF and see if any of them cause X-N to stop working.
Just a thought...
