With the synchronization function, you can synchronize your Vivaldi browser data across multiple devices.

A standalone version can be used for testing a specific setup or version, without touching the system wide settings (profile). It can also be used to create an almost fully portable installation of Vivaldi that you could store on an external disk, for sharing between computers.

Important! Since passwords and extensions are encrypted with a key which is unique to the user profile on each computer, they cannot be transferred.

The following instructions are for Windows. If you are on Linux or macOS, you can run the Snapshot and Stable versions side by side, without having to take extra steps during installation.

Installing Vivaldi as a standalone on Windows

To install Vivaldi as a standalone version:

1. Go to:
   • Vivaldi.com/download to install the stable version or
   • Vivaldi.com/blog/snapshots/ to the (most recent) blog post to download the Snapshot.
2. Open the installer from the Downloads Panel or from the folder you downloaded it to.
3. In the installation window select Advanced.
4. Under Installation type select Install Standalone.
5. Set a destination folder (anywhere except the Program Files folder)
6. Click Accept and Install to finish the installation.

To open the browser go to the destination folder > Application > vivaldi. To access the browser easily save a shortcut to your Desktop or pin it to the Start Menu or Task Bar.

We recommend that you tick the additional dialogue box “Register standalone Vivaldi” (see above). This will make the standalone version appear in the Default apps list and will be added as an entry in the Registry of the operating system.

Also, we recommend keeping the option for automatic updates enabled, to make sure you get the latest security updates, newest features and most recent bug fixes.

Updating the standalone version

If you have automatic updates enabled in Settings > General > Updates, the update will be downloaded automatically and installed on the next browser restart. Update ready message will also appear on the right side of the Address Bar when an update has been downloaded. Click on it and then on Restart to complete the update. 

To check for updates manually go to   Vivaldi menu > Help > Check for Updates and then Install Update.

You can also download the latest update from the website. Just save it to the same folder to keep the settings or create a new folder to have a clean install.

---

Uninstalling the standalone version

1. Go to the folder where you saved the Vivaldi standalone folder. If you can’t remember or can’t find it, go to Vivaldi menu > Help > About and take note of the Executable Path.
2. Close all Vivaldi windows
3. Delete the folder containing the Vivaldi standalone.
   • In case you registered the standalone version as a default app, registry keys and update notifiers (if enabled) need to be deleted manually.

Vivaldi is not made available under one unified open source license. It does contain the Chromium source code with changes made to allow the HTML/CSS/JS based UI to run. All changes to the Chromium source code are made available under a BSD license and can be read by anyone on vivaldi.com/source. Details in this regard are explained in the the README and LICENSE files within the package.

In addition, our UI code is written in plain, accessible code for those who read HTML, CSS and JS. This means that for all practical purposes the Vivaldi source code is available for audit.

Vivaldi also contains third party code. Licenses for these parts can be found in the source package and in the installed browser by navigating to vivaldi://credits.

This guide will explain how you can remove Vivaldi from your computer. Choose which operating system you are using and follow the appropriate steps below.

In this article, we’ll explain what are the causes, and what to do when encountering a “Decryption Failed: Risk of Data Loss” dialog.

Vivaldi may show a dialog on startup when it fails to decrypt an encrypted user profile. Your user profile contains your Settings, History, Bookmarks, Cookies, and more. To protect the data in your profile, Vivaldi encrypts it to prevent attackers from gaining access to your profile.

When the dialog appears, it means that the decryption secret key has gone missing or that it has been changed. Your decryption secret key is stored safely in a subsystem managed by your operating system (the key store). Vivaldi uses Keychain on Mac OS, OSCrypt on Windows, and either GNOME Secrets or KWallet on Linux. These subsystems are unique to your user account on your device; your user account password unlocks these encrypted subsystems when you log in to your computer.

You need to use the same decryption secret key on the same operating system user account on the same operating system to unlock your secure storage and successfully decrypt your Vivaldi profile.

You cannot use the same Vivaldi profile on multiple user accounts on the same computer or on different computers. Please use Vivaldi Sync to keep your data in sync between multiple instances of Vivaldi on different computers or between user accounts on the same computer.

For Linux users with multiple desktop environments, please configure all your desktop environments to use the same key store. The key store to use is derived from the standard XDG_SESSION_DESKTOP environmental variable. To override the automatic selection, you can use the launch argument --password-store=gnome-libsecret. Other supported values include kwallet5 and kwallet6. You can also disable the encryption system with basic (strongly discouraged!).

If you encounter this warning dialog, you may know what changes you have made and know how to undo them to restore your profile. Closing the dialog will exit Vivaldi and give you an opportunity to fix the problem. E.g., you might be able to export a secret key from one computer and migrate it to another. This is beyond the scope of this article.

You can also choose to continue with data loss. Selecting this option will log you out of most websites, your Vivaldi Mail and Calendar accounts, Vivaldi Sync, and more. It will also delete your saved passwords. Some protected settings may also revert to their default values. After resetting your profile, it will be encrypted using a new secret key stored in the user account on the current computer.

Your secret key may be irrecoverably lost if you reset or override your computer’s user account password.

Please note that this dialog may appear due to a common miss configuration problem: Your key store will be locked when you lock your screen or the computer hibernates; and then subsequently fails to unlock after unlocking the screen or resuming the session. This problem can happen on any operating system but is a common problem on more obscure Linux distributions or desktop environments.

Other web browsers either do not encrypt your profile or silently delete the same data without warning!
