Shouldn't this one be uplifted to Firefox69 and 68ESR?

(In reply to Alexandre Folle de Menezes from comment #9)

Shouldn't this one be uplifted to Firefox69 and 68ESR?

Yes. The patches for Beta and both ESR branches are already present (see comment #5), I normally just wait a few days before requesting uplifts to make sure no unexpected breakage did occur.
