Widevine is a “Content Decryption Module” (CDM) that provides Vivaldi with support for Encrypted Media Extensions (EME). EME are a form of Digital rights management (DRM) that are required by many, popular audio/video streaming services (Netflix, Amazon Prime, Spotify, Tidal, etc.).
Testing support
To test Widevine support, go to demo.castlabs.com and attempt to play the videos that are tagged with “DRM”.
Installing Widevine
If DRM videos will not play:
Open vivaldi://components
Locate: “Widevine Content Decryption Module”
Click “Check for updates”
Troubleshooting
If the DRM test video will still not play, file a bug report stating that you cannot play proprietary media. Mention your Operating System (including architecture and version).

Select Window with # Tabs and;
Click on Restore All to open all Tabs or on a single Tab on the list to open a specific Tab.

For a complete overview of visited pages, visit History by:
Going to Vivaldi menu > Tools > History menu;
Clicking History on the top menu on the Start Page, or
Integrate Vivaldi with the rest of your operating system’s user interface.
Use OS-based window controls.
Display the Active Tab’s full title.
Make use of macOS’ Split View feature.
Tile apps with window split view
Many modern operating systems have made it easy to tile different apps and windows on the screen.
To tile Vivaldi with other apps on Windows:
Hover over the maximize button in the top right corner.
Select your preferred tiling option.
You can also click on the Tab Bar or the native window’s title bar and drag the window to different points on the edge of the screen to snap the window to a grid.
To tile Vivaldi with other apps on macOS:
Hover over the maximize button in the top left corner.
Select your preferred tiling option.
On Linux, tiling windows and apps depends on the distro’s window manager, but many allow snapping to a tiled grid by dragging the window or using keyboard shortcuts.
In Vivaldi, you can choose how to display your tabs in a few simple steps.
Tab Bar position
The Tab Bar can be located on any side of the browser window – top, bottom, left, right. To change the position, go to Settings > Tabs > Tab Bar Position.
Toggle Tab Bar visibility
To toggle the visibility of the Tab Bar, either:
Open Settings > Tabs and untick the box for Show Tab Bar to hide it. Tick the box again to show the Tab Bar;
When the Tab Bar is either on the top or bottom of the window, you can assign a minimum tab width for the active tab. In Settings > Tabs > Tab Display, select how many pixels the width should be and then, no matter how many tabs are open, the active tab will always be easily noticeable.
If the Tab Bar is on the side of the browser window, adjust the width of the Tab Bar by placing the mouse on the edge of the Tab Bar and drag in the desired direction.
Scrollable Tabs
When the Tab Bar is placed horizontally on the top or bottom of the browser window, by default, tabs start to shrink in size, the more you open them. That can result in page titles or even favicons becoming invisible. Enabling Scrollable Tabs can prevent that. When enabled, tabs won’t shrink in size. Instead, they’ll go out of view and you can scroll the Tab Bar to browse through the open tabs.
To enable Scrollable Tabs: 1. Go to Settings > Tabs > Tab Display > Tab Bar. 2. Check the box for Enable Horizontal Scrolling.
To scroll through the tabs:
Hover the mouse over the Tab Bar and use the mouse wheel.
Click on the < > buttons on either side of the tabs.
Long click on the < > buttons to display all open tabs as a list.
In case you have enabled switching tabs by scrolling in Settings > Tabs > Tab Cycler, hold down the Shift key to scroll on the Tab Bar without switching tabs.
Loading progress indicator
When a page is loading the Address Field displays the progress. Additional loading indicators are displayed also on the Tab, which is especially useful for Tabs loading in the background.
In Settings > Tabs > Tab Display > Page Load Progress you can pick between 4 options:
Progress Bar
Favicon Progress
Favicon Spinner
None
Window Background Image
In addition to the active tab colour or Theme’s accent colour, you can show your Start Page background image on the Tab Bar. To enable it:
A “crash” occurs when Vivaldi encounters an unrecoverable error and shuts down unexpectedly or a tab’s contents disappear and are replaced with a “dead bird” image. Information pertaining to the crash is logged by Vivaldi.
Enable automatic crash reporting
When you enable automatic crash reporting, we will receive the crash logs automatically. You can enable crash reporting during the welcome flow after installing the browser, or any time in Settings.
Enable Share Crash Reports to Help Us Improve Product Quality.
Provide additional information
By adding context to the crash, the team will have an easier time fixing the bug that’s causing the crash. You can do that by filing a bug report that gets linked to your crash log.
To file a bug report about the crash:
Go to vivaldi:crashes.
Look for a crash log that was created around the time you witnessed the crash.
Click on Provide additional details. You’ll be taken to our bug report page, where the crash’s ID is already prefilled in the Summary field.
Fill out the form with information you think is relevant to the crash, such as steps to trigger the crash.
Submit the bug report.
Manual crash reporting

You will find a dated “Vivaldi_Crash_Logs” tar archive in your /tmp directory, that you can attach to your bug report.

By default, Vivaldi blocks advertisements on sites with abusive ad practices, such as ads which are purposefully misleading users and ads using abusive technologies – for example, pop-ups that prevent you from leaving the site.
The abusive ad-blocker feature can be disabled in Settings > Privacy and Security > Tracking Prevention > Block Ads on Abusive Sites, but we strongly advise you to keep it enabled.
The abusive ad-blocker gives the browser access to a blocklist which is hosted on our end-to-end encrypted servers. It is updated from the server automatically by the browser, and applied to intrusive websites without needing to contact the server each time.
If you’re looking for additional content blocking options, consider enabling Vivaldi’s Tracker and Ad Blocker or using an Extension.
Page Actions are custom filters that modify the look of a page. They allow you to make adjustments to individual webpages, and to make browsing more effective and focused on your individual needs. Page Actions are great for accessibility.
To apply an action, click on the Page Actions button on the right side of the Status Bar and select the one you want to use. Alternatively, type the action’s name in Quick Commands, or create a Keyboard Shortcut or a Mouse Gesture to toggle your favorite actions on and off.
The action will only be applied to the active Tab and won’t be disabled if you navigate to a different website in that tab. In many cases, multiple page actions can be applied simultaneously.
When you turn off a Page Action, the page will reload.
Available Page Actions
CSS Debugger – outlines various element types for a simple CSS inspection;
Filter Black and White – turns the page into black and white;
Filter Grayscale – changes the page’s colors to grayscale;

In the print preview window you can make many adjustments for the printable page.

Copies – Change the number if you need more than one copy of the page.
Choose layout – Choose between portrait and landscape.

If you prefer the system dialog for printing click on Print using system dialog.
Print with Reader View
Many websites, especially news sites, strip the printable page of irrelevant content. In case the web page you’re trying to print doesn’t do that, you can switch to Reader View, which will remove unnecessary sections and lets you print just the article. In addition, by using Reader View, you can adjust the font, font size, and line height before printing.
Print with Screen Capture
To print the whole website or sections of it, use Vivaldi’s Screen Capture tool to take the screenshot and print the saved file.
Hold down the Shift key to select multiple tabs in a row or Ctrl/⌘ key to select tabs that aren’t necessarily next to each other.
While you hold down the key, click on the tabs you want to select.
Quick Commands
Open Quick Commands (F2/⌘ E) and start typing either: Select Previous Tab, Select Next Tab, Select Related Tabs or Deselect Tabs to execute the command.
