Can't select front or rear camera on Firefox (Android) anymore

[cmar0ck]

Hi all,

since the latest Firefox updates on Android (tested on Galaxy A20e with Firefox v86.1.1) the dialog to select the front or rear camera doesn't appear anymore and the front camera is used by default.

I tried the following solutions / workarounds and also installed Firefox Nightly (v210309) to fiddle with 'about:config' but to no avail:

Is there anything I can do codewise to force the camera selection dialog to open?
