For many months now, whenever I've tried to follow a link, say, from an email, firefox opens but it tries to open a file which has been created in ~/.cache/kioexec/krun/... After months of looking for ways to fix it I still can't make it work as it should. I have a workaround which is to copy the link address, open firefox and paste the link into the url bar.
Does anyone know what my problem is and how to fix it?
I'm totally up-to-date with tumbleweed and as you can see my default browser is firefox (currently 91.0.1).
