Firefox file picker shows black folder icons

Hello! This is a fresh install of the latest Tumbleweed snapshot I have access to at this time (20240714). Anyone having similar problems? The file picker in all other apps work fine (so does kdialog --getopenfilename in a terminal:

Working KDialog:

How can I begin troubleshooting this? Thanks for your time and any answers!
Before this I had an install of Tumbleweed that was working fine (a couple days ago).

Hi! I have exactly the same problem and the worst thing is that I can’t see the thumbnails of the files either. Does anyone have a solution? Thanks!

I had the same problem and I just solved it by looking at 1226112 – Supersede kmozillahelper by xdg-desktop-portal integration

So, remove kmozillahelper and set

widget.use-xdg-desktop-portal.file-picker=1
widget.use-xdg-desktop-portal.mime-handler=1

in about:config in Firefox. Somewhere I read that only the first one, widget.use-xdg-desktop-portal.file-picker=1, is needed. I don’t know. Anyway, now my problem is solved.

I used this also. Only setting widget.use-xdg-desktop-portal.file-picker=1 works for me on any distro

Yes, you are right. widget.use-xdg-desktop-portal.file-picker=1 is sufficient
