How to prevent Firefox 89.0 from showing black-background drop down boxes?

Windows 10 v 2004 /HP 840 G3

This is new, never happened before 89.0: Chrome still shows white drop down boxes

Provisionally stopped hardware acceleration, no effect; now back on


Extensions, as have been in use for years without this issue, shown in attachment; anyway no change in troubleshooting mode

I don't care about the rest, just the menus, so I changed the single Proton value browser.proton.contextmenus.enabled to "false" and got my light menus back "
