Fast-Forward let users navigate from one document to the next related document in a series. Examples include navigating to the next page of a book, search result page, forum, or image in a gallery.

Fast-Forward is activated by pressing the Space key (enabled by default) at the bottom of the document, or by using the Fast-Forward button or Quick Command.

Vivaldi detects the next document in a series using a few different methods:

1. (Preferred web standard.) The first <link> element with a rel="next" property in the document.
2. The first <a> element with a rel="next" property in the document.
3. The last <a> element with the exact string “Next” or “Next Page” (or localized equivalents) in the document. The aria-label and title properties are also considered. Only the last 1000 <a> elements are considered.

Fast-Forward detection only happens during the initial loading of the document. Dynamic insertions later will not be detected by Vivaldi. Fast-Forward is updated dynamically when an element’s href property is updated.

Accidental Fast-Forward Navigation

Fast-Forward may be accidentally triggered on a compatible document, especially for documents and web apps like games that want to interact on the Space keyboard event.

Accidental navigation can happen when a document processes a keyboard event, but fails to consume the event after having acted on it. In your event handler, make sure to call preventDefault() to signal to the browser that the keyboard event has been acted upon and consumed. This happens automatically when using default form controls such as <input> and <textarea>.

It’s important to test for and ensure compatibility with Fast-Forward, Single-Key Shortcuts, and other keyboard accessibility features.

Vivaldi will source metadata for bookmarks from the HTML Standard metadata elements and from Open Graph Protocol metadata. This metadata is used to prefill values when the user creates a new bookmark.

The bookmark title will be sourced from:

1. The document title from the <title> element.
2. The Open Graph Protocol title (og:title).

The bookmark description will be sourced from:

1. The Open Graph Protocol description (og:description).
2. The document description from the <meta name="description"> element.

The Open Graph Protocol description is preferred as it is often a higher-quality summary of the page than the HTML Standard description. The latter is often overly long or misused to list page keywords instead of a written summary or description.

Vivaldi for Android and Vivaldi for iOS only use the HTML Standard elements.

Vivaldi Calendar is a fully-featured calendar client built into the Vivaldi Browser. Users can subscribe to calendar feeds or add a single or group of events to their calendar schedules.

Calendar feeds and event files both use the iCalendar (RFC 5545) file format.

---

Prompt to add events to Vivaldi Calendar

To prompt a user to add an event to their calendars, create a link using the https (recommended) or http URI scheme. Example:

https://example.com/staff-meeting.ics

---

Prompt to subscribe to the calendar in Vivaldi Calendar

To prompt a user to follow a new calendar feed, create a link to it using the webcal URI scheme. Example:

webcal://example.com/holidays.ics

Vivaldi will assume and only supports the HTTPS protocol for calendar subscriptions.

Vivaldi polls calendar subscriptions for updates every 10 minutes. Please ensure your calendar server sets appropriate HTTP cache response headers and supports cache-revalidation to reduce the load on the server (see RFC 9111).

Vivaldi Mail is a fully-featured email client. Email deliverability and filtering of potentially unwanted messages is left to the user’s email server.

This document describes specifics for senders who want to ensure a good recipient experience and compatibility with Vivaldi Mail

---

Email Rendering

Vivaldi Mail renders emails using the Chromium Blink rendering engine.

Vivaldi Mail blocks external resources from loading by default. Users will be prompted to approve loading external resources per sender address.

Embed small and important images, like a logo or symbol, into the email itself to ensure it is loaded. Include text alternatives (alt properties) to serve as placeholders for other external images.

Vivaldi Mail will convert HTML-only emails to plain text when the user prefers reading plain text. The conversion process preserves links and renders images as their alt property text. You can suppress an image from being represented in the plain-text conversion by explicitly marking it as decorational (alt=“”).

For the best result, supply a more carefully crafted plain-text alternative version of your HTML message.

---

Dark Mode

Vivaldi Mail follows the user’s color scheme preferences and renders email messages accordingly.

You can style the light and dark mode variants of your message using the web standard prefers-color-scheme media query. Example:

<meta name="color-scheme" content="light dark">
<style>
@media(prefers-color-scheme: light) {
  body { background: white; color: black; }
}
@media(prefers-color-scheme: dark) {
  body { background: black; color: white; }
}
</style>

Opt-Out of Auto Dark Mode

Vivaldi Mail may automatically apply a dark color scheme if your email does not contain color scheme information.

You can disable Auto Dark Mode in an email message by explicitly declaring it as light mode only.

<meta name="color-scheme" content="only light">

---

Multipart Selection

Vivaldi Mail does not support combining multiple multipart/related parts or other complex and unusual multipart messages. It will choose the largest (in bytes) suitable part of the preferred type in a multipart/alternative set.

---

Phishing Warnings

Vivaldi Mail will display an impersonation/phishing warning if the name in the From or Reply-To fields resembles an email address different than the associated sender address. Send using a human-readable name or no name set instead.

Vivaldi Mail will display an impersonation/phishing warning if the email addresses in the From and Reply-To fields are at different domain names (including subdomains). Vivaldi Mail will always display an impersonation/phishing warning if either of the two addresses is at a common personal mailer domain (e.g., gmail.com and icloud.com).

---

Threading

Vivaldi Mail is designed around email threads. Threading ensures related emails are grouped and displayed together. Vivaldi Mail follows standard email threading conventions, as described in RFC 5322 section 3.6.4.

Please consider adopting email threading for your automated status updates to transactional emails. E.g., an order shipping confirmation should be a reply to the order confirmation email.

---

Calendar Invites

Vivaldi Mail will process calendar event attachments in the iCalendar (RFC 5545) file format and will prompt the user to respond to pending invitations (RSVP).

Alternatively, you can link to event files on a web server. See Integrating with Vivaldi Calendar for Web Developers.

Tab Notifications let webpages communicate brief numeric status summaries to users. Examples include displaying new unread messages, emails, or news items; unprocessed tasks or bills; or the number of items added to a shopping cart.

Tab Notifications are displayed as numeric badges on top of the document’s favicon on the Tab Bar and Web Panels.

Vivaldi detects numeric counters at the beginning of the document title when they’re surrounded by parentheses (U+0028 LEFT PARENTHESIS and U+0029 RIGHT PARENTHES) and separated from the remainder of the title by a space (U+0020 SPACE) character. Example:

<title>(7) Webmail</title>

Tab Notifications is enabled by default, but users can disable it.

The badge is updated dynamically when the document’s title changes. For the best performance, update the document.title property or update the <title> element’s innerText property. Replacing the <title> element may cause badge updates to be delayed.

Numbers with two or more digits may be displayed as a plus-sign badge instead of a numeric badge due to space constraints.

The numeric counter is removed from the document title in user interfaces where the badge is displayed. The character sequence “(0) ” is removed from titles but does not generate a badge.

Tab Notifications are only detected from the top-frame document title (no frames).

Opt-Out of Tab Notifications

You can disable Tab Notifications in a document by prefixing the title with a zero-width space (U+200B ZERO WIDTH SPACE) character. Example:

<title>&#x200b;​(1195) Step Counter</title>

Vivaldi lets users either select text inside links or drag the links around. The behavior in Vivaldi differs from the default in other Blink (Chromium) browsers.

Users can select text inside links by clicking on a link and dragging left or right. The link element becomes draggable when they drag it up or down.

To explicitly make a link always draggable in any direction, set its draggable attribute to true. Example:

<a href="https://example.com/" draggable="true">
  Draggable and Not Selectable Link Text
</a>

To explicitly make a link’s text always selectable in any direction, set its draggable attribute to false. Example:

<a href="https://example.com/" draggable="false">
  Selectable and Not Draggable Link Text
</a>

When links are not explicitly draggable (the default), the CSS user-select property is ignored, and their cursor property may be ignored.

Vivaldi on desktop is known for its many customization options and we’ve brought many of them over to Vivaldi on iOS as well.

To change the browser’s theme in Vivaldi on iOS:

1. Go to the  Vivaldi menu > Settings > Appearance & Theme > Browser Theme. 
2. Choose between:
   • following the system,
   • Light theme,
   • Dark theme.

If you choose the light theme, the browser toolbars will adapt its accent colors according to the website colors.

Accent Color

You can customize the theme further by choosing an accent color for the browser toolbars. When you have the Tab Bar enabled, it will be in your chosen accent color. When the Tab Bar is hidden, the Address Bar (and if it’s at the bottom of the screen, then also the bottom toolbar) will be in the accent color.

To choose an accent color:

1. Go to the  Vivaldi menu > Settings > Appearance & Theme > Accent Color. 
2. Choose between:
   • One of the preset colors,
   • Inherit Accent Color from page,
   • Custom color – insert the color’s HEX value or tap on the color wheel in front to use a grid, spectrum, or sliders to pick the color.

---

Custom Start Page Wallpapers

Just like on desktop, you can select a preloaded wallpaper to decorate the Start Page or use your own image.

To update the wallpaper:

1. Go to the  Vivaldi menu > Settings > Appearance Start Page > Wallpapers. 
2. Tap on the wallpaper of your choice or on the + button to select an image from your Photos.

---

Dark mode for web pages

If, in addition to the app’s user interface, you also wish to view websites in dark mode:

1. Go to the  Vivaldi menu > Settings > Appearance & Theme > Website Appearance.
2. Select between:
   • Light,
   • Dark, or
   • Auto.

Some websites do not offer their site in dark mode. In that case, you can force dark mode, by selecting the “Dark” option and enabling Force a dark theme on all websites.

Like the desktop browser, Vivaldi on iOS has a unique user interface.

Tab Bar

On the Tab Bar, you can see all your open Tabs, just like on desktop. If you have a lot of Tabs open, swipe left or right on the Tab Bar to see the rest of the tabs.

To enable/disable the Tab Bar:

1. Go to  Vivaldi menu > Settings > Tabs.
2. Toggle on/off Show Tab Bar.

To move the Tab Bar to the bottom of the screen together with the Address Bar:

1. Go to  Vivaldi menu > Settings > Tabs.
2. Select Bottom for Address Bar Position.

---

Address Bar

•  Content blocker – change the tracker and ad blocking level for the website.
• Address and Search field – type in the link you want to visit or a search term you want to look up.
•  Vivaldi menu – access options such as Bookmark Page, Settings, and much more by tapping on the Vivaldi logo.

To move the Address Bar to the bottom of the screen:

1. Go to  Vivaldi menu > Settings > Tabs.
2. Select Bottom for Address Bar Position.

When moving the Address Bar to the bottom it’s recommended to reverse the order in which search suggestions are displayed and keep the most relevant suggestion closest to the Address Bar.

To reverse the order of search suggestions:

1. Go to  Vivaldi menu > Settings > Tabs.
2. Make sure Bottom is selected for the Address Bar Position.
3. In Search Suggestions, enable Reverse search suggestion order.

---

Bottom Toolbar

•  Panels – access your Bookmarks, History, Notes, and Downloads.
•  History back – move back in history of visited pages.
• Focus on the Address Field to start a search or enter a website address. In the Tab Switcher, you’ll see a New Tab button in that place.
•  History forward – move forward in history of visited pages.
•  Tab switcher – view all open, private, synced, and recently closed tabs.

When you’ve moved the Address Bar to the bottom, there will be two toolbars at the bottom of the screen. In case you have the Tab Bar enabled, at the bottom of the screen, the Tab Bar will replace the bottom toolbar.

In landscape mode and on larger screens, such as on the iPad, all the icons from the bottom toolbar are moved to the Address Bar.

Sessions are a way to store your open tabs for easy access later. It allows you to close some unused tabs or all of them – freeing up memory and resources on your computer. A Session can contain tabs from a single window, all your windows, and optionally your Workspaces. Learn how to manage your Sessions using the Sessions Panel.

Access the Sessions Panel

To open the Sessions Panel:

• Click on the  Sessions panel button on the sidebar.
• Type “Session Panel” in Quick Commands.
• Create a Keyboard Shortcut or a Mouse Gesture for the action.

---

Add a New Saved Session

To save tabs as a session via the Sessions Panel:

1. Open the Sessions Panel.
2. Click on Save Tabs as Sessions near the top right corner of the panel.
3. Give the session a name.
4. Decide, whether to include tabs from all Workspaces in the session or not and whether to save tabs from all windows or only the current window.
5. Click Save.

---

View and Edit Sessions

To see and edit the contents of a saved session:

1. Open the Sessions Panel.
2. Select a session.
3. Click on Edit Session in the top right corner of the panel.

You can rearrange, rename, and remove tabs as you would with the active session in the Windows Panel.

---

Auto-save Sessions

To automatically back up all your open tabs as a session once every hour:

1. At the bottom of the panel, click Automatic Session Backup.
2. Select how many days worth of backups you want to keep:
   • Last day
   • Last 3 days
   • Last 5 days
   • Last 30 days

---

Delete a Saved Session

To delete a session:

1. Open the Sessions Panel.
2. Select a session you want to remove.
3. Click on Delete Session near the top right corner of the panel.

Alternatively, right-click on the session and select Delete from the context menu.

When you encounter an issue and you’re trying to determine whether you can fix it yourself or need to report a bug, follow the steps below. Remember that in many cases it’s important to reload the web page or restart the app for any changes to take effect.

Restart the app

Sometimes the simplest things help, so exit the browser, and hopefully on restart the issue will be gone.

To exit Vivaldi on iOS, open your device’s app switcher and swipe up on Vivaldi to close the app.

If you’ve kept your mobile device on for a long time, restarting the device may help as well.

---

Update the app

In case you’ve turned off automatic updating of apps, check for updates manually from the App Store or from the app store you installed Vivaldi from.

---

Disable Tracker and Ad Blocker

Website functionality may depend on elements with trackers that are blocked by the Tracker and/or Ad blocker. Click on  Content Blocker on the left side of the address bar to disable blockers and test the website.

To change blocking settings globally, go to  Vivaldi menu > Settings > Tracker and Ad Blocking > Default blocking level.

---

Delete Browsing Data

Websites get updated all the time, but information about the old version of the site is still stored in cache files and Cookies. This may cause discrepancies in the displayed website and occasionally even break functionality.

In addition, storing old browsing data for a long time will use up your device’s memory space, so deleting it every now and then can have a positive effect on the browser’s speed as well.

To delete browsing data in Vivaldi on iOS:

1. Go to  Vivaldi menu > Settings > Privacy and Security > Clear Browsing Data.
   Alternatively, go to Panels > History panel and tap on Clear Browsing Data at the bottom right corner of the screen.
2. Select the data you want to delete and a time range.
3. Tap on Clear data.

---

Reset flags

Experiments are a great way to test new features that are being developed. But these features are hidden behind flags for a reason – they can still be buggy. If you’ve experimented with flags and suddenly Vivaldi doesn’t work as it should or crashes altogether, go back to the default settings.

To reset flags:

1. Go to vivaldi://flags;
2. Tap on Reset all in the top right corner;
3. Tap on Relaunch at the bottom of the window to restart the browser.

On rare occasions, the browser needs to be restarted twice for the experiments to be fully reset.

---

Check iOS settings

iOS operating system’s settings may affect, how Vivaldi functions. Check and change the settings that might affect Vivaldi and test the issue again.

---

Disable other apps

In case you’re using apps that can affect Vivaldi (e.g. VPN), try browsing with them disabled to see if the bug is still there.

---

Test the Snapshot version of Vivaldi

Sometimes the bug you’re encountering has already been fixed and is being tested in the Snapshot version of the browser. In that case, you just need a little patience until the fix is released in the Stable version.

On iOS, you can install the Snapshot version of the app from TestFlight.

---
