History

The History tool in Vivaldi is somewhat different than in a typical browser – instead, Vivaldi’s History is a detailed overview backed by statistics and presented in a fresh, visual way. It was built to give users a powerful and useful tool to explore their browsing patterns and to make finding previously visited sites easier than ever.

Browsing History in Vivaldi

Accessing History

To open the History page:

History Panel in the Vivaldi browser

Using History in Vivaldi

Uninstall Vivaldi on Windows 10

If you have issues uninstalling Vivaldi while using Windows 10, Windows 10 provides two different UIs to add/remove programs: the old style UI, and a new modern look (see screenshots below).
Only the older style UI will allow a non-admin user to uninstall a single user installed program.

Uninstall Vivaldi on Windows 10's old UIOlder add/remove program Windows UI

Uninstall V on Windows 10's new UINew add/remove programs UI in Windows 10.

 

To uninstall Vivaldi from Windows 10, make sure that you are using the old add/remove UI.
To ensure that you are, follow these steps:

    1. Use ⊞ WinKey+R to open the Run dialog,
    2. Type: control appwiz.cpl,
    3. Press OK,
  1. Scroll down to the “Vivaldi” entry and double click it.

Alternatively, you can also uninstall the browser by using the setup.exe we include with Vivaldi and calling it directly, e.g. assuming the version number is 1.7.735.29, start the run dialog and then issue the following:

%LOCALAPPDATA%\Vivaldi\Application\1.7.735.29\Installer\setup.exe --uninstall --vivaldi

If you still run into issues when attempting to uninstall Vivaldi from Windows 10, please get in touch with our support team on vivaldi.com/contact.

Other operating systems

If you use macOS, Linux or another version of Windows, head here for instructions on how to uninstall Vivaldi.

 

Capture a Screenshot

Vivaldi’s built-in Capture tool lets you capture either a Full Page screenshot, or a Selection of the screen that you define. It can be accessed in a number of ways through the Vivaldi UI to give you flexibility in how you implement the tool.

Types of Capture

Full Page

A Full Page capture is a screenshot of the full length of a website (max 30 000 pixels). Whether you’re giving feedback on a design, gathering inspiration, or just want to share an interesting site with a friend, this is a great way to get a bird’s eye view in a single image.

Selection

Capturing a Selection lets you focus in on a particular piece of your screen for more precision. After doing an initial selection, you can resize the capture area, before taking the screenshot.


Output of Capture

Whether capturing a Full Page or a Selection, you can choose to save the new snap to your disk for later use, or copy it to your clipboard to share it instantly.

Save to Disk

In the Capture tool you are given options to “Save as JPEG” or “Save as PNG“. When choosing these options, your new screenshot will be saved immediately to your local disk.

Copy to Clipboard

A newly captured screenshot can be copied as an image to your system’s clipboard. This makes it easy to share your new screenshot in other applications and documents immediately; once a screenshot is copied to your clipboard, simply Paste in place to insert the image into the desired location.

Share captured screenshot on other apps

Create a new note from the capture

When you save the capture as a note, the screenshot will be saved with the capture date and page URL. The note won’t have a title or any text content, so go to the Notes Panel or Notes Manager to add it.


Access the Capture tool

Vivaldi lets you choose how to use its features, giving you several ways to get something done. Capturing screenshots is no exception. Below we describe the ways which you can access the Capture functionality in your browser.

Status Bar

Capture can be accessed in your Status Bar via the camera icon. Clicking on the icon will bring up your options for capturing a new screenshot: Full Page vs Selection, “Save as…” and “Copy to Clipboard“.

Capture menu

Keyboard Shortcuts

Capture functionality can be activated using Keyboard Shortcuts in Vivaldi. This means that pressing a pre-defined combination of keys will fire the associated action (e.g. capturing a Selection screenshot).

To map a custom keyboard shortcut to your preferred Capture method open your Settings and search for “Capture”. The available actions that can be mapped to a keyboard shortcut will display in the search results.

Click into the action you’d like to work with, and type your custom shortcut. The command is available immediately.

Notes

Vivaldi has a built-in Notes tool which allows you to capture thoughts and ideas while you browse. The Capture tool is integrated directly in the Notes Panel, allowing you to attach screenshots to your notes.

take-screenshots-in-notes

Quick Commands

Quick Commands is a tool for users that like to keep their hands on the keyboard. To access the Capture tool via Quick Commands:

  • Open Quick Commands by pressing F2 / ⌘ E.
  • Enter “Capture” to filter the list of available commands.
  • Use arrow keys to navigate the list of Capture commands.
  • Press Enter to issue selected command, or
  • Close Quick Commands by pressing Escape key.
capture-quick-commands

Change the location of saved captures

When you select the option to “Save as PNG” or “Save as JPG“, your capture will be stored at the directory specified in Settings. The location where your captures will be saved can be edited in Settings > Webpages > Image Capture > Capture Storage Folder.

Naming the Capture

Captures will be named automatically, but you can define the format in Settings > Webpages > Image Capture > Capture File Name Template.

Create a new Tab Stack

Option 1

  1. Click and start dragging one tab over another or over an existing Tab Stack;
  2. When the second tab is dimmed, release the mouse button.

You can adjust Stacking Drop Delay in Settings > Tabs > Tab Features > Tab Stack Options. Make it longer, if you often accidentally create Tab Stacks, when dragging tabs from one place on the Tab Bar to another.

  1. Right-click on a tab;
  2. Select Stack Tabs by Hosts.

Option 5

It’s possible to create a new Tab Stack automatically with the active tab and any new tab you open from a link in the active tab. To enable this feature:

  • With Popup Thumbnails enabled, hover the mouse first over the Tab Stack for the thumbnails to appear, then drag the thumbnail from the stack to the Tab Bar.

Ungroup a Tab Stack

To unstack tabs:


Tab Stack display

In Vivaldi, Tab Stacks can be displayed either on the same level as other tabs or on a second level.

Compact Tab Stacks

All tabs are on the same level. The Tab Stack, regardless of how many tabs are in the stack, will take up the same amount of space as other tabs.

To switch between tabs, click on the small tab indicators above the Tab Stack or hover over the stack and click on the tab’s thumbnail you want to open. In case you don’t see the thumbnails, check Settings > Tabs > Tab Display > Tab Options, to make sure Popup Thumbnails are enabled.

Two-Level Tab Stacks

Tabs in a Tab Stack are displayed on the second level and you can use Tab Features (e.g. hibernating, cloning, muting, etc.) the same way you’d use them on regular, ungrouped tabs.

The second level is only displayed when one of the stacked tabs is the active tab. To always show the second level, click on the padlock button on the far right of the Tab Bar (bottom on vertical Tab Bar) to lock it in place.

Accordion Tab Stacks

All tabs are on the same level. When the Tab Stack is collapsed the stack is almost the same width as a regular tab. When the Tab Stack is expanded, the tabs in the stack will share the available space on the Tab Bar with all other tabs.

The stack will expand automatically when viewing a tab in the stack and collapse, when viewing other tabs. To keep the Tab Stack open, click on the Expand/Reduce Tab Stack button or double click on the collapsed Tab Stack. Don’t use the latter option in case you have enabled closing tabs on double click.

The Tab Stack is surrounded by a border to help you visually distinguish the tabs in the group.


Rename Tab Stacks

Option 1

  1. Double click on the Tab Stack;
  2. Give the Tab Stack a name;
  3. Press Enter or focus elsewhere in the browser.

In case Close Tab on Double Click has been enabled in Settings > Tabs > Tab Handling or Minimize Active Tab has been enabled in Settings > Tabs > Tab Features > Tab Cycling, it’s not possible to start renaming a Tab Stack with double click.

Option 2

  1. Right-click on the Tab Stack;
  2. Select Rename Tab Stack from the context menu;
  3. Give the Tab Stack a name;
  4. Press Enter or focus elsewhere in the browser to save the new name.

Pin Tab Stacks

Pinning a Tab Stack prevents it or any of the tabs in the stack from accidentally being closed. The pinned stack will be located at the beginning of the Tab Bar on the left or top, depending on your Tab Bar location.

To pin a Tab Stack:

  1. Right-click on the Tab Stack on the Tab Bar (or Window Panel).
  2. Select Pin Tabs.
    Pinned Tab Stack will have the most recently visited tab’s favicon.

To unpin a Tab Stack:

  1. Right-click on the Tab Stack on the Tab Bar (or Window Panel).
  2. Select Unpin Tabs.

Alternatively, type (Un)Pin Tabs in Quick Commands or create a Keyboard Shortcut or Mouse Gesture for the action.


Additional Tab Stack Features

When you right-click on a Tab Stack, you’re presented with some useful options. In addition to the ones covered above, you can also:

  • Bookmark all tabs in the stack. The new bookmarks will be grouped into their own Bookmarks folder.
  • Copy all links allows you to create a list of links you can share with others or save in a document somewhere.
  • Save the stack as an Individual Session.
  • Tile all tabs in the stack for side by side view.
  • Reload all tabs in one go.
  • Hibernate the stack to save browser resources.
  • Move the stack left or right on the Tab Bar, to a new window or another Workspace.

Preview Tabs

Previewing tabs lets you find the page you’re looking for easily by showing you a screenshot of the page in a thumbnail.

Pop-up thumbnails

To preview a tab, move your mouse pointer over the tab in the Tab Bar. A visual preview of the tab’s contents will appear below. This feature can be enabled/disabled in Settings > Tabs  > Tab Display > Tab Options > Show Pop-up Thumbnails.

Pop-up thumbnails for Tab Stacks

When you’ve grouped tabs into a Tab Stack, hovering over the stack on the Tab Bar will show you the thumbnails for all tabs in the stack. You can close tabs from there and drag tabs out of the stack to the Tab Bar or new Window. Alternatively, right-click on the thumbnail and select Close Tab or Remove from Tab Stack from the context menu.
