Vivaldi Feed Reader helps you discover more feeds on popular sites that have made their feeds difficult to find.

Memory Saver helps reduce memory usage by automatically hibernating tabs that haven’t been used in a while. This way, active tabs, such as those used for gaming or streaming, can run more smoothly.

How much memory will be saved depends on the number of tabs you have open and how much memory they use. Also, how soon a tab is hibernated varies (especially with the Automatic option). Tabs that you rarely visit will be hibernated a lot sooner than the ones you view often. Tabs playing media, including forms, updating frequently (e.g. a mailbox), etc. will be kept active for longer.

To enable Memory Saver:

1. Go to Settings > Tabs > Memory Saver.
2. Select your preferred option:
   • Disabled
   • Automatic (recommended)
   • After 1 Hour Idle
   • After 2 Hours Idle
   • After 3 Hours Idle
   • After 6 Hours Idle

To reactivate a tab just go to it and it will reload. Due to this, you may lose your place on the page.

While Memory Saver puts tabs into hibernation automatically, you can still hibernate background tabs, Tab Stacks, and Workspaces whenever you need it by right-clicking on a tab, Tab Stack, or Workspace and selecting the hibernation option from the menu.

Memory usage per tab

To see how much memory a specific tab uses in real time, hover over the tab on the Tab Bar to display the Tab Thumbnail. The thumbnail preview also lets you know when a tab is hibernated.

If you don’t see Tab Thumbnails on hover, go to Settings > Tabs > Tab Display > Tab Options and make sure Show Popup Thumbnails has been enabled.

On Vivaldi Social, you can automatically hide posts that you find offensive, deal with sensitive matters, just oversaturate your timelines or you don’t wish to see for any other reason.

To create a filter:

1. Go to Preferences > Filters.
2. Click Add new filter in the top right corner.

Vivaldi can import and export Notes to a Markdown+Front Matter files (.md file extension) and directory structures. Vivaldi can also import plain text files (.txt file extension).

You can import your notes through the File: Import menu and export through the File: Export menu.

Notes will be exported while recursively preserving the notes folder structure in your file system. When importing notes, the selected notes directory is imported recursively while preserving the folder structure as notes folders.

On import, all files are assumed to be Markdown formatted, regardless of file extension. Unrecognized file extensions are ignored during import. Note attachments cannot be imported or exported. (We hope to include this in a future version.)

Vivaldi preserves note metadata — including a note’s title, associated URL, creation- and modification time — as a Front Matter preamble.

During import, all metadata and the entire Front Matter preamble is optional. The file name will be used as the title if the title is not provided in the metadata.

A Front Matter preamble consists of three hyphens on the first line of the file followed by a line break. Metadata is then listed as colon-separated key-value pairs which are separated by line breaks. The preamble is terminated by another sequence of three hyphens followed by a line break. Unrecognized keys in the Front Matter preamble are ignored.

Metadata dates should be in the ISO 8601 datetime format. Other formats may lead to unexpected results.

Example file with the complete set of recognized metadata keys:

title: Example Title
url: https://example.com/
date: 2024-02-19T07:30Z
lastmod: 2024-02-21T15:09:58Z

I'm a *bold* Markdown note!

Products: Vivaldi for desktop.

Vivaldi can import and export the Reading List to a comma-separated values (CSV) file. The data structure is a table which is interoperable with the Instapaper CSV file format.

You can import your reading list through the Vivaldi menu > File > Import from Applications and Files and export through the Vivaldi menu > File > Export > Export Reading List.

The file must comply with RFC-4180 and have a .csv file extension. Please note the special requirements in RFC-4180 for table fields containing any of the following characters: comma (,), double-quote ("), and line breaks (carriage returns and line feeds).

The first line of the file must be the following exact table header declaration:

URL,Title,Selection,Folder,Timestamp

Each reading list entry is defined as a table row following the above schema. Each row is separated by a carriage return and a line feed character. A complete example is included at the bottom of this document.

The URL and Title columns contain the URL and title of the reading list entry. The URL must be unique and a valid absolute URL. On duplicate URL values, Vivaldi will keep the last use of the URL.

The Selection column is unused in Vivaldi.

The Folder column. Vivaldi only supports two values for the Folder column: Unread for all unread entries, and Archive for all read entries. Unrecognized or empty folder names will be treated as Archive on import.

The Timestamp column is a POSIX timestamp associated with the reading list entry. For example, the date it was added to the list or its state last modified. Vivaldi uses the reading list entry’s last modification time.

Example file:

URL,Title,Selection,Folder,Timestamp
https://example.com/,Example,,Unread,1708327800
https://example.net/,"Escaped, ""Title""",,Archive,1708327800

With multiple mailboxes and probably thousands of emails, finding the correct one can be tough. Vivaldi Mail’s search function makes it easy to pin down the one you need in just a few steps.

Search messages

To search through everything, just type something relevant to the message you’re looking for in the search field and Vivaldi will show you all the relevant email messages.

To narrow down the search, use the various search filters that appear as soon as you’ve started a new search. The options include:

• Searching through all messages or specific accounts or folders.
• Specifying the date range.
• Looking for senders or recipients (From, To, CC).
• Search by the email subject.
• Search by something in the body of the message.
• Showing only messages that include attachments.
• Use the conjunction NOT to only find messages that do not match with the search keyword.

From View Filters you can further choose whether to display read messages, and messages from Custom Folders, Mailing Lists, Archived, Feeds, Spam, and Trash folders.

To reset the search filters, click on Clear Search.

---

Save searches

Frequently performed searches can be saved as Filters.

To save a search:

1. Review the search keyword(s) and filters.
2. Click on Save as Filter, below the search filters.

Once the search is saved as a filter you can add actions to it.

1. Go to Settings > Mail > Mail Filters and Actions.
2. Select the saved search filter.
3. At the bottom of the filter settings, click Add Action.
4. Choose the action. For example, add a label, mark as read, etc.
5. If you wish, add more actions by clicking the + button next to the current action.
6. Finish by clicking Update Mail Filter.

Depending on the operating system you’re on, installing Vivaldi may differ a little.

Installation options

Click on Advanced in the top right corner of the installer window to reveal various options.

Language

Choose the language you want the browser’s user interface to be in. The chosen language will also be used as the default translation output language and websites may use it to determine which language to show the site content in.

Installation Type

• Install for all users – The browser will be installed for all user accounts on the operating system.
• Install per user – The browser will be installed only for the current user.
• Install standalone – The browser is self-contained within a single folder including all user data and, unless made available as a default app, won’t be added to the operating system’s registry. Choose this option, if you already have Vivaldi installed and want to create an independent or portable version of the browser. You can read more about the Standalone version here.

Additional options

• Destination folder – Shows the executable path for the browser. User data (browser profile) is stored in the default system location. In case of standalone installs, the destination folder will contain both the application files and user data.
• Make standalone Vivaldi available as a default app – Enabling this option will add the browser to the operating system’s registry, so it can be used to quickly open various file types from the operating system and other apps.
• Disable automatic updates (not recommended) – By default Vivaldi will download updates automatically and install them on the next browser restart. When disabled, you’ll have to check for and download updates manually.

To make Vivaldi the default browser:

In case you see Vivaldi is set as your default browser instead of Set as Default button in General settings, then Vivaldi already is your default browser.

---

Default browser check on startup

When Vivaldi isn’t your default browser, every time you open the browser you’ll be asked whether you want to make Vivaldi the default browser. To disable that notification:

1. Go to Settings > General > Startup > Default Browser;
2. Disable Check on Startup.

Vivaldi Social brings together speakers of many languages. While it’s fascinating to know what people are up to in various parts of the world, it can be challenging if you don’t speak their language.

To help you cross language barriers, Vivaldi Social uses the translation service powered by Lingvanex, a service familiar to those who use the Vivaldi browser.

Translate posts

Posts on Vivaldi Social will be translated to the language you’ve chosen for your user interface. You can change the user interface language in Preferences > Appearance > Interface language.

To translate content:

1. Find a post on Vivaldi Social you want to translate.
2. Click on the Translate button below the post.
3. Click on Show original, to revert to the original text.

If a post is in a different language, but you don’t see an option to translate it, then the post’s author hasn’t set the correct language for their post. In that case, you can use the built-in translator in the Vivaldi Browser to translate the post.

---

Make your posts translatable

To make sure your posts are translatable, always make sure you’ve chosen a matching language for your post’s text.

Set a default posting language:

1. Go to Preferences > Other > Posting defaults > Posting language.
2. Choose the language you post in most.

If you’re posting in a different language from your default, change the language settings in the post editor:

1. Below the text field, click on the current language code (for example, ).
2. From the drop-down menu, select the language you’re posting in.
