FWIW I tried to duplicate the issue and this is what I found:
First, when asking for another image, instead of changing the letters only the clutter changes, the letters remain the same.
Second, when asking for audio both PaleMoon and Firefox Plugin Containers crashed when trying to open the VLC plugin, C++ thingy stopped in an unusual way or something like that. I have both Disconnect and Adblock Latitude active on PaleMoon, but the Firefox is plain vanilla for testing purposes. Iron Portable could reproduce audio, so basically it works.
