I found this article from Martin Stransky: https://mastransky.wordpress.com/2019/01/08/fedora-firefox-heads-to-updates-with-pgo-lto/
It appears Fedora's Firefox package is build with PGO. Is Ubuntu's .DEB package built with PGO as well?
There's also this documentation from Mozilla: https://firefox-source-docs.mozilla.org/build/buildsystem/pgo.html
