I think the solution given before my post (download tab on Chrome) does not work. At least on my computer.
I use this (on Chrome as well, but should work on any browser):
-press F12 (tools for developers)
-ctrl+F
-type "mp4" if looking for vids (sometimes "mov") or "jpg" (for pictures)
-to the right of where I typed the previous words you will see how many files of that type there are in the page (example, you will see "1/15", meaning there are 15 files of that type
-scroll through them with the up/down arrows right next to those numbers
-on the upper window, the file you chose will be highlighted
-mouse right botton: "open in new tab"
-this should open a new tab just containing the chosen file
-hoover over the file (vid or pic), mouse right click "save as"
This works like charm for me. I hope I did explain it properly. If not, let me know and I´ll clarify further.
