No veo nada raro en ese log, sería bueno que sacaras uno de Autoruns como te he comentado antes, para ver "eso" que inicia con Windows.
Por otra parte, ¿has intentado ejecutar Firefox en modo seguro? y con eso me refiero a tanto el modo seguro de Windows, como el modo seguro de Firefox

Saludos
en el modo seguro (del pc) he intentado pasar mi AV (tengo que pasarlo de nuevo tenia problemas lo desinstale y volvi a instalar ayer) y no, no he abierto el firefox en modo seguro: no obstante aquí va el log de autoruns..
