SLT File Extension

Mozilla User Profile Folder – file format by Mozilla

SLT is a file extension associated with the Mozilla User Profile Folder created by Mozilla. It stores user data, settings, and preferences for Mozilla applications like Firefox and Thunderbird, allowing customization and personalized experience.

SLT File Format

An SLT file, or Mozilla User Profile Folder, is associated with the Mozilla Firefox web browser. It stores user-specific information, such as browsing history, bookmarks, cookies, and extensions. SLT files are typically hidden from the user and are located in the user’s profile folder. When a user creates a new Firefox profile, a new SLT file is automatically generated.

SLT files are used to store all of the user’s personal settings and data, including:

  • Bookmarks and history
  • Cookies and cache
  • Extensions and themes
  • Passwords and autofill information
  • Preferences and settings

SLT files are essential for the operation of Firefox, as they allow users to save their personal settings and data. If an SLT file is deleted or corrupted, the user will lose all of their saved information.

Understanding Mozilla User Profile Folder (*.SLT)

Mozilla User Profile Folder (*.SLT) files are profile repositories for Mozilla Firefox, SeaMonkey, and Thunderbird email client software. These files contain user settings, preferences, history, cookies, extensions, and various other configuration data related to the respective software’s usage. SLT files are typically located in the user’s profile directory on the local computer and are essential for preserving and managing individual user profiles.

Opening SLT Files

SLT files cannot be directly opened or viewed without using the corresponding Mozilla software. When a Mozilla application is launched, it automatically loads and uses the SLT file associated with the current user. If needed, users can manually open their SLT file using the Mozilla software’s profile manager. For example, in Firefox, go to the “Hamburger Menu” (three horizontal lines) > “Help” > “Troubleshooting Information” > “Open Folder” next to “Profile Directory.” This will open the user profile directory, where the SLT file can be viewed or modified (not recommended unless necessary).
