Vivaldi lands Sync functionality in latest browser snapshot

The most recent snapshot of the Vivaldi web browser comes with integrated Sync functionality to sync data across devices.

The much awaited functionality makes it easier to keep data such as settings, passwords or extensions in sync automatically.

While Sync landed in the Vivaldi 1.14 snapshot, it is not yet a given that the functionality will land in the next stable version of the web browser as well.

Vivaldi staff will monitor the feature closely and base the decision on how it performs both on the user side but also on Vivaldi's side as infrastructure is required to maintain the Sync functionality of the browser.

Vivaldi Sync first look

You need to create a Vivaldi account to get started with Sync. Simply go to the "join the Vivaldi Community" page to create an account if you don't have one already. Once you have confirmed the account you are ready to get started with Sync in Vivaldi.

You do need to have installed the latest snapshot release, at least version 1.14.1030.3 of the browser, to test Sync functionality.

Load the Sync settings in the browser vivaldi://settings/sync/ and enter your Vivaldi username and password.

You may get an error message right now telling you that the login to the sync server failed with an Internal Server Error, Gateway Time-out, or other errors. If that is the case, wait until the issue is resolved by Vivaldi.

If you can sign in to Vivaldi Sync, you get the following options on the Sync page:

  • Enable automatic synchronization of all data.
  • Select specific data (bookmarks and speed dial, settings, passwords, autofill, history and remote sessions, extensions, notes) that you want to sync.

The page furthermore displays the last synchronization date and time, and whether the data syncing to the server and from the server were successful.

You need to set a specific sync password which is used to encrypt the data that is sent to the server, and to decrypt it when it comes from it. The password never leaves the local browser, so that Vivaldi or anyone else cannot access Sync data on the servers due to encryptiom

Data is uploaded to Vivaldi's infrastructure, and synced with any device running the browser if you sign in with the same Vivaldi account.

The lead engineer of Sync notes that Vivaldi modified Chromium's synchronization engine by using end to end encryption for the data, and by modifying it so that additional data types may be supported in the future.

I asked Vivaldi to provide me with additional information on the security and privacy of Vivaldi Sync, and will update the article as soon I get a reply.

Vivaldi Sync works in the following way: when a particular data type is synced, Vivaldi's Sync engine pulls all entries from the server, decrypts them, and merges them with the data found in the Vivaldi browser. New entries are added, all is encrypted, and then set to the server.

Vivaldi users may load vivaldi://sync-internals in the browser's address bar to get detailed information on Sync in the browser.

Vivaldi hopes to release a standalone Sync server in the future to give users the option to run their own server independently from Vivaldi's infrastructure.

      Well it is a bit difficulty to distinguish between domains and files for instance.

      I know a service made by google that is similar to Google bookmarks.

    @Ashwin–Thankful you delighted my comment; who knows how many “gamers” would have disagreed!

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
