[Bug 1796661] Re: Firefox can't download files to an fscrypt protected, unlocked folder

[Troels Liebe Bentsen]

The issue is because firefox does a rename from the /tmp folder to the
encrypted home folder, right now fscrypt returns EPERM instead of EXDEV
that would be normal when the operation can not complete because of
crossing a mount point or in this case unencrypted to an encrypted
folder.

The upstream firefox bug is here:
https://bugzilla.mozilla.org/show_bug.cgi?id=1521041

But one could argue that the kernel interface is broken and it should
return EXDEV as tools like mv also breaks, there are some patches in the
works but I don't know how far they are, maybe ubuntu could carry them
until they go upstream:

https://patchwork.kernel.org/patch/9943001/
