moOde 5 Beta 1

[TheOldPresbyope]

On the audio config page when selecting "Edit Options"  there is a brief screen flicker and no options are presented...

This is a continuing interoperability problem with Firefox (possibly only on Ubuntu ?) which has open bug reports for 'Expand Filesystem' and Piano 2.1 options menus not opening.

Seems that whatever new coding used to 'pop-up' the 'Edit Options' may be a clue to this problem ??

Meanwhile the workaround is use another browser...Chromium works.

Running the Developer's web console, I see Firefox throwing a warning which I click the "Edit Options" button

Code:

Empty string passed to getElementById(). jquery-1.8.2.min.js:2:10384

Don't know if that's directly related to your problem but it doesn't occur in Brave, Chrome, Opera, or Vivaldi, all of which work with the moOde config panels. This on Linux Mint which is a derivative of Ubuntu.
Firefox on my Nexus 9 phone (Android 8.1.1) also "refuses the gate" on these options, but there's no easy access to any Developer Tools.
If you don't want to load Chrome try one of the other browsers.
