Exact steps to reproduce:

use secureblue, which is a Fedora variant using hardened_malloc

github.com/secureblue/secureblue

I am using the variant with user namespaces enabled

Comment 2

I could reproduce this using a freshly downloaded firefox-bin too. But here it showed an error and that it saved a crash report
