Videos posted on facebook can't be opened in the mobile site..every time I click on one, firefox always opens a blank tab and no video shows up. This has been a problem in Firefox Android for quite awhile. The videos that wont open are only those directly uploaded by any user or page...this does NOT include shared videos from Youtube and other pages. Those open fine..... But someday id like to be able to view vids posted by other people without this blank page nonsense.
