I have been using NZBGet on a number of devices for some time without any issues. Recently though I am getting the following error message when opening NZBGet in Firefox
TypeError: can't redefine non-configurable property "userAgent"
This is on a Windows 10 machine running the latest version of Firefox. I am not a very computer literate person and this has me puzzled. The error message appears at the top of the screen and I will not be able to see the download queue (but I get a message saying 10 files on another page are selected). Nothing will show in the error log files either. If I reload the page or restart NZBGet things may or may not go back to normal. NZBGet still works fine in MIcrosoft Edge browser on the same machine.
Does anyone have an idea as to how I can fix this? I already tried uninstalling and reinstalling Firefox.
