Hi segfault

That takes care of  /dev/video0  and  /dev/video1.  It also takes care
of  /dev/video/  but not its contents. Try it like this:

--- Code: ---sudo chown -Rv tc:staff /dev/video*
--- End code ---
That also should recurse into the directory and change its contents
as well as report what it is doing.

Thanks Rich.  :)

I did as you said, but the error persists. I also did "dmesg | grep video" and I can see that bcm2835-isp and bcm2835-codec is registered on multiple /dev/video<number> (which makes sense because the camera does work when snapping photos using CLI) then I checked which PID firefox has using "ps" and "fuser /dev/video<number>" and firefox does show up as a being connected to these video files.

I'm starting to doubt that it's a permission thing... but what else could it be?

I'm using:
sudo chown tc:staff /dev/media*
sudo chown tc:staff /dev/dma_heap/*
sudo chown -Rv tc:staff /dev/video*

And when firefox asks me which camera to pick it shows unicam (along with bcm2835-isp, etc) which is the same device picked when running "libcamera-jpeg -o ~/camera.jpg --width 640 --height 320 --nopreview".

EDIT: it's not related to firefox extensions either I think, because I've not installed any  ;) and also tried running in -save-mode

curaga:
FF usually has an about: page with more detailed errors. Try finding if there's one for the camera.
