Default Downloading video clips on Facebook

My friend & I have exact same setup same phones, htc m7, same ROMs, InsertCoin SixthSense, same apps.

When she is in facebook app & taps on the a video, she has options to view & download it with ES file explorer. while I don't have that option.
If I do the same as her, my facebook's videos are just played on the screen.

Any tip is appreciated.
