Firefox 19 llega con mejoras - Pronto en CentOS y SL desde el repo "remi"

Se ha liberado Firefox 19 con algunos cambios, yo lo he probado y si, han fixeado fallas en el motor js, dado que algunas apps lo hacian colgarse al 18.0.2, al 19 no, desde lo que probé desde el .tar.bz2
En el repo de remi, para CentOS, SL o algún clon estará entre hoy por la noche y mañana, en Fedora casi de forma instantanea.
