If all that you wanna do is download stuff, maybe try https://cobalt.tools
It pretty much just grabs the raw URL to the content for you, without the UI and fluff (in the case of Instagram) so you can just do a little "save as..." and it's worked quite reliably for me to view content my friends sent me.
I've had success with this before for unlocking :)
