Fb no longer permits to set external browser as default to open links?

I can find many guides about this, and I also remeber I had this setting enabled. I mean the possibility to make Facebook use your default browser to open articles/links, by default.
Looks like the setting has been wiped out in one of the latest updates, or is just me to not find it anymore?

It's probably the Facebook app not identifying itself as a browser any more.
