Regarding PGO benefits for Firefox, there is a thread: https://groups.google.com/g/mozilla.dev.platform/c/wwO48xXFx0A/m/ztg4i0DYAAAJ that shows measurable improvements from PGO.
Anyway, since the issue is quite old. Is PGO still disabled for Firefox in Ubuntu repositories? Maybe things have changed during these years...
