Vivaldi Browser

Download Forum

TechCrunch: (January 27th 2015):

“The former CEO of Opera, Jon von Tetzchner, has released the Vivaldi Browser for fans of the old Opera. This initial release is a Technical Preview, it is neither feature complete, nor free from bugs that might spoil your day. It uses the Chromium rendering engine like the new Opera 38. It already has Panels, Tab-stacking, Notes, Speed Dial, and Customisable shortcuts and Tabs. Built-in email is planned, but mail is limited to web mail at the moment.”

Vivaldi has been my default browser for over seven years. It has some great features that boost my productivity like a built-in Email Client, customisable shortcuts, Web Panels, Notes, Tab Tiling, and Tab Stacking.

Some Useful Topics

Site Settings

Click the site info icon in the address bar to display a popup menu showing the settings for the current site. On a secure (https:) site the icon will be a padlock; on an insecure (http:) site, the icon will be an information icon.

The Cookies link on the popup gives details of the cookies set for the current site, and lets you block, allow, or remove them.

The Certificate link (on secure sites) gives details of the certificate: its expiry date, issuing authority, etc.

The Site Settings link opens a tab with all of the site settings: Autoplay, Location, Camera, Microphone, Motion sensors, Notifications, JavaScript, Images, Pop-ups and redirects, Ads, Background sync, Sound, Automatic downloads, MIDI devices, USB devices, Serial ports, File editing, HID devices, Protected content IDs, Clipboard, Payment Handlers, Insecure content, Third-party sign-in, Augmented reality, Virtual reality, Your device use, Window placement, and Fonts.

The shield icon, to the left of the padlock or site information icon gives access to Ad-blocking and Cookie tracking (see below).

Page Tiling

If one or more tabs are selected, the tiling icon is active, allowing the tiles to be tiled horizontally, vertically, or as a grid. Tiling can also be removed if it is already enabled for the current tab. Tiles can be resized by dragging the separator.

Search Engines

Add your own search engines to your favourite websites. I have one to search my own website:


I have others to search the Pali Text Society Dictionary. English words can be searched too, to provide a reverse English to Pali dictionary lookup.

Any search engine can be used by typing the search string in the address field preceded by the nickname. Note, however, that if you have a search engine with the nickname “a” and try to search for a string like “a day in the life,” the results will be for “day in the life” using the engine with the nickname “a” — in my case that would be a search with Acronym Finder. To search with my default search engine, Ecosia, I would have to type “e a day in the life,” in the address field.

In Settings, Search, one can choose to show the search engines as a field in the address bar, as a button like in my screen shot, or disable it entirely.  

In Settings, Search, enable Show Search Engine Icon to make selection easier.

Image Toggle

Images can be hidden or displayed on the current page, or only cached images can be shown.

Page Zoom

The Zoom Slider allows the page zoom to be changed with the range 20% to 500% in 10% increments. Any value in that range can be set by entering it in the zoom field to the right of the slider. Click on Reset to change it back to whatever default value you have set in Settings, Webpages. In Settings, Appearance, Use Buttons in Range Controls, to choose between a slider and buttons. This affects all controls that have a range slider.

Page Actions

Mouse-over and click to preview page actionsVivaldi has a Page Actions button <> at the bottom right of the interface, just to the left of the Zoom slider. I moved it to the top, next to the URL field, for greater convenience using Shift+Drag.

Click the <> icon to show a popup menu akin to User Style sheets in Opera 12.18. I have added one user style sheet for Video Brightness as some YouTube videos are too dark to watch comfortably.

Filter Invert helps those who prefer white text on a black background, or black text on white for sites that use a dark colour scheme.

Filter Black and White may be useful for colour-blind users if a site uses text on coloured backgrounds that is hard to read.

The Filter Obscure option offers some privacy if someone is looking over your shoulder. Moving the mouse cursor over the page shows the page content, while move the cursor over the UI hides the page content.

Transform 3D may help a colleague to read the page content if they are sitting beside you. The 3D effect is removed on moving the mouse cursor over the UI.

Vivaldi uses CSS for the page and interface elements. The Page Actions apply CSS styles to the page. Custom page actions must be backed up and reinstalled to the \Application…\resources\vivaldi\user_files\ folder after upgrading Vivaldi.

Ask on the forums if you need help on using CSS. Almost anything can be changed if you know how. Changes to custom.css modifications (apart from Page Action user styles) are retained on installing updates if you follow the recommendations given below.


Vivaldi has all of the most important features: Auto-update, Bookmark import from Opera 12.18 and other browsers, customisable shortcuts and mouse gestures, concatenate commands, tab-stacking, expand/collapse tab stacks,  and find in page. Tab tiling is an excellent feature that already exceeds what could be done in Opera. The built-in email client has replaced my old email client in Opera 12.18, which I seldom launch nowadays.

The developers release regular snapshots, fixing bugs and adding new features. Bookmark the Vivaldi Snapshots Blog or subscribe to the RSS feed to keep abreast of the latest developments. On the help menu, check for updates, to see if you have the latest version of whichever development channel you use — Stable or Snapshot. The update check will happen automatically on launching Vivaldi. You can opt to install now or skip and update on restarting Vivaldi.

The image below shows how tiles can be resized by dragging. The Toggle UI shortcut (default = Ctrl F11) will hide toolbars, which can be shown again with other shortcuts. Click the image to see the Vivaldi window with a vertically tiled tab-stack showing the previews, which update to show the current page view. Tab stacks can be closed with the close button, and each tab in the stack has its own close button on the tab preview. Two or more tabs in a stack can be tiled vertically. Stacked tabs can be pinned by using a shortcut, but pinned tabs cannot yet be stacked.

Click to View Larger Image of Vivaldi Window


These are usually web pages designed for mobiles, which are narrow enough to look good in the side panel. A YouTube Channel or play list can be used to watch videos or listen to music while you are working. Copy the URL of the page, and add it to the side panel in Vivaldi.

Vivaldi has a built-in Translation Panel, which is powered by the Lingvanex translation engine. The text is hosted on Vivaldi’s own servers to ensure privacy. There is a button to clear the current text, and another to clear the history of translated passages. Selecting text on the page automatically adds it to the panel. There is a long list of supported languages. Automatic language detection needs more than just a few words.

The Downloads Panel shows download progress, and can be sorted by name, type, size, date added, date finished, or address. In later versions all panels can have their own separate width, and the order of Web Panels can be changed with drag and drop.

This search filter can be added as a panel and used to find existing feature requests before adding yet another duplicate that only needs to be moved and locked by the moderators.

The Bookmarks, Downloads, and Notes Panels have a details pane at the bottom of the panel. There is a separator between the main panel and the details pane. Drag the separator to resize the pane. Double-click or middle-click the separator to show/hide the details pane.

Select a download to view its size, source, destination, download time and progress.

Select a note and disable markdown to switch to the note editor, or open the full page Note Editor by double-clicking a note, or right-click the Note Panel Icon to open it in a new tab.

Select the Window Panel to view all tabs in the current window, and a list of the last 100 closed tabs.

See this forum thread for some more Web Panels recommended by Vivaldi users.


The Chrome Web Store lists hundreds of extensions that can be added to Vivaldi. To add extensions open the Extensions page with the default shortcut Ctrl+Shift+E, or from the Tools menu. To manage extensions, look at the options in Settings, Address Bar, Extension Visibility. Visit the Vivaldi Extensions forum for recommendations, advice, and support.

I use just three regularly:

I keep the latter disabled as it can cause problems on some forums! Be mindful that some extensions can cause problems as well as solving them.


Blocking List Management

Desktop and Android versions can block ads and tracking cookies on a per/site basis. An icon can be seen in the Address Field. Click this to see the Tracking Protection level for the current site. Open Settings, Privacy, to Manage the Default Settings, or access them directly from this popup. Tracking and Blocking Lists can be added or deleted in Settings, Privacy, Manage List Rules.

Improved Tab Dragging for Two-level Stacking

It seems that a lot of users have difficulty adjusting to the implementation of tab dragging, which was designed for use with two-level tab stacks. The animation is no longer smooth, and has been replaced with a dotted outline to show where the tab will be dropped.

I think this makes it easier to use. I made this short video to illustrate the moving, stacking, and unstacking of tabs. As this is a newly added feature it will probably get improved when the developers have time to fix it.


A few experimental features can be enabled by going to the URL vivaldi://experiments. These experimental features may change, break, disappear, not work as intended or at all. Please proceed with caution.

There is a forum dedicated to creating modifications using CSS and JavaScript. Here are a few that I use, which were created for me by others more familiar with CSS. They are all stored in a file named custom.css, which I saved in the Vivaldi installation folder. To enable Custom UI Modifications enter vivaldi://experiments into the address field and enable the flag: “Allow for using CSS Modifications.” In Settings, Appearance, select the path to tell Vivaldi where to look for custom CSS files, and restart the browser. Now, any changes will be applied on restarting Vivaldi. Note, that since this is an experimental feature, there is no guarantee that it will continue to work in later versions.
