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/ ** Bug watch added: Mozilla Bugzilla #1521041 https://bugzilla.mozilla.org/show_bug.cgi?id=1521041 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1796661 Title: Firefox can't download files to an fscrypt protected, unlocked folder Status in firefox package in Ubuntu: New Bug description: My Downloads folder is encrypted by fscrypt. I can save and read files in there. However, for Firefox - all downloads fail and it says only "download failed" and offers a button to retry which fails again. After a failed attempt, a file is created with a proper file name but no content (0 bytes). When I changed the download dir to a different non-fscrypted folder, everything works properly and files do get properly saved. I switched to Chromium and Chromium has no problems downloading files into any dirs, regardless encrypted or not.
