Android 12 and up supports opening multiple windows of the same app. This means that if you have a newer mobile device, you can browse with Vivaldi in multiple windows just like on desktop.
Open a new window
Multiple windows are supported better on devices with larger screens, such as tablets. To open a new window on a tablet or a phone with a width larger than 600dp:
Open the Vivaldi menu.
Select New Window.
Though not as convenient, you can open a new window on a smaller screen by following these steps:
Open Vivaldi.
Open your devices app switcher.
Long-press on the Vivaldi logo above the app preview thumbnail to open a split-screen view.
Search for Vivaldi and tap on it to open a new window in the other half of the split screen.
Exit split screen view, for example, by swiping the divider all the way up or down the screen.
When checking the app switcher, you’ll see Vivaldi listed twice or more, if you’ve opened even more windows.
Switch windows
To switch windows:
Open the Vivaldi Menu.
Select Manage Windows.
Select the window you want to focus on.
Move a tab to another window
To move a tab you have open in one window to another window:
Main Menu in Vivaldi on Android gives you access to most of Vivaldi’s key features and tools.
Access the Main Menu
Whether you’re using the browser on a small phone screen, a large tablet screen or from your car’s center console, the menu can always be accessed from the right side of the Address Bar. Just tap on the Vivaldi logo to open it. The options available in the menu depend on whether you have open a web page or the browser’s Start Page.
To close the menu, tap on the feature you want to use or on an area outside the menu.
Customize the menu
On smaller screens, in the Main Menu, there’s a menu bar with 5 of the most important menu options. There’s more screen real estate on larger screens, so the menu bar is not available on tablets and the like. Since the importance depends on the person using the browser, you can customize the menu bar to fit your needs.
To customize the menu:
Go to Vivaldi Menu > Settings > General > Menu Settings.
Choose between the 2 presets or make your own menu.
To put together your own custom layout for the menu bar:
In the Main Menu Layout settings, choose the third option, Custom layout.
Move the menu items you want to see on the menu bar to the first 5 positions in the list. To reorder menu items, long press on the item you want to move and drag it to your preferred position.
On desktop, Ctrl+F / ⌘ F is a well known Keyboard Shortcut for searching through the open web page. On mobile devices, where the screens fit even less content in the visible area, being able to just search for a keyword is even more useful.
To search in Vivaldi on Android:
Open the Vivaldi menu.
Select Find in Page.
Enter your search keyword.
Search results will start showing as you type. Use the arrows in the top right corner to move to the previous and next results. Tap on the , when you’re done with your search.
Hover the mouse over your username or avatar in the top right corner of the page

Trouble updating the profile?
If after clicking Update on the profile you see an error messages, for example, ‘Can’t verify the user‘, try updating the account again in a Guest Profile or a new User Profile. An Extension or some Setting may cause the issue in the browser’s main profile.
In case updating account information didn’t work in a clean profile either, please report the issue to us using the contact form below.
Error message after submitting the registration form
Go back, check that all information is correct and try again. Refresh the page and start again, if necessary.
Try disabling Extensions (especially privacy, security and/or content blocking extensions) to see, if any of them hinder the browser’s work.
Check the status of our services on status.vivaldi.com to see if everything is operational.
Make sure Cookies for Vivaldi.net sites have not been blocked.
Clear Cookies & Storage, Cache, and Application cache from History.
Haven’t received the account activation email?
Make sure a valid email address was entered in the registration form. In case you might have made a typo in the recovery email or gave an invalid email, please contact us below with your account’s username, the email you signed up with and what the email address should be. We’ll fix it for you.
Check all mailbox folders, including the Spam folder, for an email with the title “Vivaldi.net – Account Activation”.
Be patient. Occasionally, email service providers queue emails, so the email might arrive in your Inbox with a delay.
Accidentally closed the activation page?
In case you leave the account activation page, you can return to it by trying to log in to your account on Vivaldi.net. On the activation page you can also request a new code should the one you had have expired.
Account activation failed?
After activating the account you should be asked to log in and then you should find yourself on your account’s profile. In case the code wasn’t accepted (e.g. it had expired), request a new code and try again.
Sometimes Extensions can cause trouble, so try if after disabling them account activation works. For example, dark mode extension, Dark Reader, is known to break functionality on Vivaldi.net, but there may be other extensions as well. You might have to restart the browser for the change to take affect.
Login issues
When instead of being logged in you’re asked to enter a 6 digit code, it means that you haven’t activated the account yet. If you just registered, check your recovery email to find the code. In case the code has expired, request a new one by clicking on the resend link on the activation page or request a new email here.
For login it’s best to use your username, but your Vivaldi email address is also accepted. In case you don’t remember the username, send a username reminder to your recovery email address.
Reset the password with your username. Please note that, password reset won’t work, if the account is locked or hasn’t been activated yet.
In case you’ve already tried logging in with the wrong password at least 5 times, the account will be locked for 5 minutes as a security measure. After the 5 minutes have passed, reset the password to access the account again.
If you only recently registered and are having issues with login to Vivaldi Webmail, you might not have built enough reputation for your account yet to be granted access. In that case, keep being an active member of the community and try again some other time.
Check the status of our services on status.vivaldi.com to see if everything is operational.

If the hashtag you’re going to use consists of multiple words, capitalize the first letter in each word, for example #VivaldiBrowser.
Mentions
You can tag other users in your posts. If you write their username as @name, the user in Vivaldi Social’s instance will be tagged (if a user with that username exists). To tag users from other instances, you also need to add their domain in the username, for example, @[email protected]. After having typed @ and at least two characters, you’ll see suggestions of users you can mention below the text field.
Emojis
You can insert emojis to your post by clicking on the laughing face in the top right corner of the text box and selecting one from the menu.
Alternatively, you can type : and the emoji’s name to insert it, followed by :. For example, type :heart: to insert ❤️. As you type you’ll see suggestions you can select.

Before publishing the poll, also select the expiration time – 5 minutes, 30 minutes, 1 hour, 6 hours, 1 day, 3 days, or 7 days.

Content warnings
Whether your post and accompanying media contains spoilers of a popular TV-show, is of sensitive nature that some might not want to see or you just want to collapse a long post and only show a bit of it, you can use the content warning setting.
When enabled, you’ll need to add a warning title, which will be visible to everyone. To see the main content, users will need to click on the post. Giving your post a content warning will automatically mark any media you add as sensitive as well and display it blurred unless clicked on.
To only give shared media a content warning, tick the box for Mark media as sensitive after having attached the media. To mark all media you post now and in the future as sensitive enable it in Preferences > Other > Posting defaults.
