Hi Chuck,
I am having a problem with FEBE using Waterfox 56.0, whereby when FEBE attempts to backup my Waterfox files, I get a beach ball spinning followed by
the attached error message. Even when I attempt to set / change FEBE preferences, Waterfox crashes.
I set up a new Waterfox profile and added FEBE as the only add-on, yet the same problem occurs.
Hope you can help out with this, please.
My computer is running Mac High Sierra 10.13.1 / Waterfox 56.0
