Hi there,

Is it two tabs with webpages loading? Is it set to default Firefox homepage? If not Please ensure that your homepage for Firefox does not contain two URLs or is not split using a "|". (You can change it from the settings>>general>>home page)

What webpages does it open upon startup? Please do send a snapshot of the problem you are facing.
