From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know about this in depth, but from what another user in this thread said, a flatpak can't ask a portal to have access to two files at once. If I'm understanding correctly, that would explain why Librewolf needs permission to access ~/Downloads, since it can be downloading more than one file at once, and it needs access to all those files in ~/Downloads at the same time.
EDIT: I got a bit mixed up with what you were saying, but nevertheless, if this is true, then Librewofl would still need permission to access ~/Downloads and so be marked as "potentially unsafe".
Ah, thank you for the explanation, I think I get it.
