You could also use deb-get (really helpful tool btw) to get it Although in the case of Librewolf it just automates adding the repos, I think...

Unfortunately I cannot find it using deb-get?
deb-get list shows all that are available. Perhaps not available for your Distro? What are you running?
@franzpow Could it be that a browser need to be uptodate or ESR to be secure. Librewolf doesn't to my knowledge provide an ESR version. Does Debian keep the other browsers uptodate, most software in Debian is the version of the time of the release. But I suppose browsers are an exception?
Afaik there are also browsers like linxs that are not ESR
