PLEASE Allow Unsafe Browser an option to download and save files to persistent volume

I’m finding a critical problem in my use of TAILS is inability for the Unsafe Browser to download and save files where I can retreive them.
Some servers refuse the TOR browser, so the user is forced to switch to the Unsafe Browser.
And if the user needs to download some files from that site, there is no way to do that!
So the user is left with one browser which is blocked for access, and one browser which blocks itself from saving files, and ultimately no way to download a file from a server which rejects the TOR browser!
I had this problem today trying to download a manual from the samsung.com website today. I have to switch OS or go without that manual because I can’t download it in TAILS.
I don’t know how other users deal with this but I find it extremely frustrating to be blocked from doing a basic function.
