So I followed LibreWolf installation instructions for RHEL
However, upon executing on these steps, it didn’t seem to work for SecureBlue specifically. I believe there is likely something in SecureBlue processes that require a different method. I didn’t see the repository pop up in /etc/yum.repos.d so I suspect something is different for SecureBlue compared to traditional Fedora SilverBlue
Answering my own question - wanted to post this for others in case they need to do the same.
SecureBlue seems to require that I manually add the repository myself. Its pretty simple.
cd /etc/yum.repos.d
run0 wget https://repo.librewolf.net/librewolf.repo
rpm-ostree update # validate the repo is pulled
rpm-ostree install librewolf
systemctl reboot
Why are you installing inferior browser when default is better?
Trivalent is a chromium based secure browser. I use that for most cases when I log into sites, while I use Mullvad Browser for anonymous browsing.
However, I’ve found Trivalent just doesn’t work in some scenarios and I need a fallback. And if I’m falling back, I’d rather use LibreWolf personally.
Thats odd, since it worked for me not too long ago with the instructions we give 
Maybe in terms of security compared to Chromium based ones, but not in other regards.
I just tested it and for secureblue you need to run
run0 -i dnf config-manager addrepo --from-repofile=https://repo.librewolf.net/librewolf.repo
rpm-ostree install librewolf
Also make sure you have https://secureblue.dev/faq#unconfined-userns on
Hmmmm, I gave that a go and it didn’t work prior, strange. Regardless I was able to get it installed.
