Portable vs Installer — Which one should you use?
Quick answer: Use the installer for everyday Windows users who want automatic updates and system integration. Use the portable build when you need a no‑install, no‑admin workflow or a disposable profile on removable media.
Overview
This page explains practical differences between the official installer and the portable distribution of LibreWolf for Windows. We'll cover installation, updates, privacy implications, portability, and recommended workflows for different user types.
Quick comparison
| Aspect | Installer | Portable |
|---|---|---|
| Requires admin | No (standard installer) — creates shortcuts and file associations | No (no admin required) — runs from folder or USB |
| Updates | Automatic or manual via installer/winget | Manual update — replace binary or use portable updater |
| Profile location | %APPDATA% (user profile by default) | Profile inside portable folder or specified path |
| Registry / system integration | Yes (shortcuts, default browser option) | No—keeps system clean |
| Use case | Daily driver on a dedicated device | Temporary use, tests, shared machines, USB |
Detailed pros & cons
Installer — Pros
- System integration: start menu, default browser option and file associations.
- Easier updates: use winget or built-in installer updates for security patches.
- Better for users who want a permanent browser with consistent profile and extensions.
Installer — Cons
- Touches system settings (shortcuts, optionally registry) — may be undesired on locked machines.
- Requires occasional maintenance for updates on large deployments (use winget for automation).
Portable — Pros
- No installation required — copy and run. Useful when admin rights are not available.
- Isolated profile: keeps data and preferences inside the portable folder.
- Easy to test or run multiple versions side‑by‑side.
Portable — Cons
- No automatic updates by default — manual replacement required.
- Performance on USB drives may vary; av software may scan portable files.
- Less convenient for daily use on a single machine.
Recommended workflows
Everyday user: install the official installer and enable updates via winget or installer to keep security current. For enterprise deployment, use winget or centralized management.
Power user / tester: keep a portable build on USB for testing or temporary sessions; backup profile folder to preserve bookmarks & settings.
How to switch profiles (portable → installed)
- Locate portable profile folder (usually inside the portable directory).
- Copy the profile folder to %APPDATA%\LibreWolf\Profiles\
- Start the installed LibreWolf with -profile
to confirm migration. - Verify extensions and privacy settings after migration.
Verifying downloads & checksums
Always verify the integrity of the build before running. Official checksums are shown on the Download page. Example PowerShell command:
Get-FileHash .\librewolf-150.0.1-1-windows-x86_64-setup.exe -Algorithm SHA256
Privacy considerations
Both builds include the same privacy-focused defaults (telemetry disabled, hardened prefs). The core difference is where the profile & update logic live. See Telemetry and Privacy Settings for precise controls.
