<p>We are often asked to implement new features of the Persistent Storage: Tor Browser preferences, Tor configuration, desktop background, mouse and touchpad settings, and so on. See the [[!tails_gitlab groups/tails/-/issues?scope=all&utf8=✓&state=opened&label_name%5B%5D=C%3APersistence desc="list of issues about the Persistent Storage in our GitLab"]].<p>
*Tor Browser* can only access the *Tor Browser* subfolder in the *Persistent* folder. You can only save your downloads to the *Persistent/Tor Browser* folder. To upload a file, you must copy it to the *Persistent/Tor Browser* folder first.
<p>Since Tails 4.13 (November 2020), <em>Thunderbird</em> uses its own OpenPGP keyring, different from the keyring used by <em>GnuPG</em> and <em>Kleopatra</em>. You don't need to enable the GnuPG feature anymore if you only use OpenPGP encryption in <em>Thunderbird</em>.</p>
<p>The packages included in Tails are carefully tested for security. Installing additional packages might break the security built in Tails, so [[be careful with what you install|additional_software#warning]].</p>
All the files in subfolders of */live/persistence/TailsData_unlocked/dotfiles* are also linked in the corresponding subfolder of the *Home* folder using Linux symbolic links.
A shortcut is provided in the left pane of the *Files* browser and in the **Places** menu in the top navigation bar to access the */live/persistence/TailsData_unlocked/dotfiles* folder.
<p>The Dotfiles feature only links specific files, and not entire folders, from the Persistent Storage. Accordingly, empty folders are ignored, as shown in the above example.</p>
On Tails and Linux in general, the name of configuration files often starts with a dot and are sometimes called [[!wikipedia dotfiles]] for this reason.The Dotfiles feature of the Persistent Storage makes it easy to persist such "*dotfiles*", for example */home/amnesia/.gitconfig* or */home/amnesia/.bashrc*.
<p>The anonymity of Tor and Tails relies on making it harder to distinguish one Tails user from another. In some cases, changing the default settings can break your anonymity.</p>
