我已经按照他们网站上的说明从终端安装了 jellyfin。我正在运行一个 firejailed 的 Firefox 并尝试为 jellyfin 设置一个媒体库文件夹，但我只能访问我的 /home/username 文件夹（我想要的文件夹是另一个：/home/username/folder-i-想）
我的 firefox.profile 文件在 /etc/firejail 中找到（为我想要的文件夹添加了白名单规则，例如，如果我尝试从 firefox 保存页面，我就会得到该规则）：
# Firejail profile for firefox
# Description: Safe and easy web browser from Mozilla
# This file is overwritten after every install/update
# Persistent local customizations
include firefox.local
# Persistent global definitions
include globals.local
# NOTE: sandboxing web browsers is as important as it is complex. Users might be
# interested in creating custom profiles depending on use case (e.g. one for
# general browsing, another for banking, ...). Consult our FAQ/issue tracker for more
# info. Here are a few links to get you going.

所以我认为问题出在 jellyfin 和 firejail 之间，也许我也应该将某些缓存目录列入白名单？有任何想法吗？使用费多拉。
