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 for any changes to take effect.

Restart the browser

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

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

---

Make sure the browser is up to date

If you’re using an older version of the browser, there’s a chance that the bug has already been fixed and you won’t be having the issue in the latest version of Vivaldi. So make sure to update your browser regularly.

You can also check recent Snapshot changelogs on our Snapshot blog. The latest fixes and newest features are tested in Snapshots, before being released in the Stable version of the browser. Then you need to wait until the next version of Vivaldi Stable is released.

---

Test in a different profile

On desktop, sometimes an Extension or a specific Setting can cause the issue. To check if that’s the case, test the website or feature in a Guest Profile or in a new User Profile.

Click on the User Profile button (the image can also be your chosen avatar or Vivaldi account’s profile picture) on the Address Bar to create a new profile or open the guest window.

---

Test in another browser

It is possible to install a second version of Vivaldi to test the issue. It’s best to test with the newest version of the browser, i.e. the Snapshot, as the likelihood of the issue being fixed is highest there and in that case, you just need a little patience until the fix is released in the Stable version. On Windows, you can install any version as a Standalone. On macOS and Linux, you can run the Stable and Snapshot versions side by side.

Since Vivaldi is based on Chromium, we sometimes inherit bugs from upstream. If that’s the case, you’ll likely be able to reproduce the bug in other Chromium-based browsers. In that case, please report the bug to the Chromium team.

Change the reported User Agent

Some websites make sure to check from which browser you’re viewing their pages from and based on the information may alter what you see. The websites may also block access to their content and features altogether. To check whether a website is displayed differently because you’re using Vivaldi, you can change the browser’s Sec-CH-UA identity and check the website again.

To change which browser brand is reported:

1. Go to Settings > Network > User Agent Brand Masking.
2. From the drop-down menu, select whether you want the browser to identify itself without a brand, as Vivaldi, Google Chrome, or Microsoft Edge.
   In addition, you can set up a custom brand by entering the browser’s brand and version number manually.
3. Restart the browser for the change to take effect.
4. Visit the website again.

---

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.

---

Disable Extensions

Extensions are a common cause of issues on the desktop browser. That’s one of the reasons Vivaldi has so many built-in features – so your browsing experience won’t be hindered by extension compatibility problems.

To disable Extensions go to Vivaldi menu > Tools > Extensions and toggle all Extensions off from the bottom right corner of each Extension card.

If the issue doesn’t occur with disabled Extensions, start enabling them one by one and test in between each re-enabled Extension.

---

Disconnect from VPN

Whether you’re using the built-in Proton VPN in Vivaldi or another VPN service, disconnect/pause the connection and reload the web page to see if the issue still persists.

---

Disable Hardware Acceleration

In case the issue you’re facing is related to playing videos and other media or to the user interface’s appearance and responsiveness, you can go to Settings > Performance and see if disabling Hardware Acceleration makes a difference. Remember to restart the browser before testing the issue again.

---

Enable (Third-Party) Cookies

Cookies are used for a lot more than tracking users’ browsing habits. Sometimes websites require Third-Party Cookies to display content that was originally posted on a different site. For example, embedded videos or Vivaldi Blog’s comment section.

In Vivaldi, third-party cookies are blocked by default in Private Windows. To review and change your cookie settings, go to Settings > Privacy > Cookies.

---

Check your security software

Make sure your anti-virus product is up to date and not blocking Vivaldi. If your anti-virus product warns you about dangers in Vivaldi, it’s most likely a false positive. In that case, review your anti-virus product settings as they might be too sensitive. Read more about it in our answers to common security-related questions.

---

Reset settings

If the browser works as expected in a new User Profile with default settings, try resetting the settings in your main profile.

To reset settings:

1. Open Settings.
2. Go to the settings category you want to reset.
3. Scroll to the bottom of the section.
4. Click Reset [category name] Settings to Default.
5. Confirm the decision by clicking Reset Settings in the popup dialog.

Some Settings, such as Enable Mail, Calendar and Feeds, will not be reset.

---

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 Cache and Cookies on desktop, click on the Clear Browsing Data button in the top-right corner of the History manager or go to Vivaldi menu > Tools > Delete Browsing Data.

Delete all site data per website

If the issue is only occurring on a particular website you can opt for deleting Cookies and Site Data just for that site.

1. Open the website.
2. Click on the Site Info button on the Address Bar and select Site Settings from the menu.
3. In the Usage section, click on Clear Data on the right.
4. Confirm, by clicking Clear in the dialog.
5. Reload the web page.

Delete Cookies and Site Data by cookie site

1. Open the website.
2. Click on the Site Info button on the Address Bar and select Cookies and site data > Manage cookies and site data from the menu.
3. Next to the listed sites, click on Delete saved data from [site name] for each item you want to delete.
4. Click Done.
5. Reload the page.

Delete Cookies in Settings

1. Go to Settings > Privacy and Security > Cookies > Saved Cookies.
2. Click on Show Saved Cookies.
3. Scroll through the list of cookies or use the search box to filter out cookies by the website domain.
4. Hover over the cookies you want to delete.
5. Click on Delete Cookies button that appears on the right side.

In order to improve the result of ad monetization for sites where a user has decided to enable ads, Vivaldi has now included support for ad attribution. You can read more about why this change was implemented here.

This page mainly aims to describe how Ad Attribution is implemented and explain the choices that led to this implementation. The goal is to be fully transparent about what may be allowed through and when.

As with the rest of the ad blocker code, this implementation is fully available as part of our released source code bundles. This allows you to fully verify that our implementation is as described here and in other articles.

Allow Ad Attribution rules

The main challenge with ad monetization is that many ad providers rely on known trackers in order to prevent click fraud and ensure that conversion has occurred before paying out. The only solution to this is unfortunately to allow such trackers to load, regardless of what our tracker blocking lists say. However, we also want to ensure that these trackers are not loaded as part of general browsing.

In order to satisfy all these requirements, I have extended the normal ad blocker rules format. This is the same format used by all popular ad-blockers and rules lists. The extended format consists of three new options that will be detailed below.

This implementation was chosen as it allows us to reuse most of the ad-blocker functionality to effectively accomplish the goal of ad attribution while also allowing us to use the automatic update mechanism coming with ad blocker rules lists. This ensures that we can promptly fix any mistake.

How it works

Ensuring that ad attribution works is a complex task that takes multiple steps to accomplish. In general, the focus is on the site which uses ads for support, however most of the work is done after clicking on a given ad. As part of the implementation, we go through the following states.

1. Navigating to a site which the user wants to support.

When this occurs, the ad attribution implementation records that it should be looking for ad clicks. We say that it is primed.

Ad attribution is normally primed on any site where the ad blocker is disabled, regardless of the state of the tracker blocker. Priming ad attribution means we will check whether the next navigation is an ad click. It has no other effect.

In order to be able to support ad attribution for our partner search engines even when ad blocking is enabled for all sites, we introduced the attribute-ads rule option:

@@||partner-site.example.com/page-i-want-to-Support$attribute-ads

This causes ad attribution to be primed on the matching page, regardless of the ad blocker status. In practice, we would also add a document option (identical to the document allow rules supported by AdBlockPlus), in order to allow the partner site to show ads:

@@||partner-site.example.com/page-i-want-to-Support$attribute-ads,document

2. Matching an ad when Ad Attribution is primed.

When this occurs, the ad attribution implementation will examine the URL being loaded as well as the URLs of any redirections which occurs as part of loading.

If none of those URLs matches a known ad, then ad attribution remains disabled. It may be primed again if the site where the user ends up is one the user wants to support.

If the URL matches a known ad, then ad attribution moves to the next stage and the process continues.

The ad-query-trigger option is used to indicate that a rule should be used to match ad URLs:

||advertiser.example.com/ad-URL$ad-query-trigger=&click-id-param=|&other-click-id-param=

The ad-query-trigger option takes a value that is composed of several query string fragments, separated by |.

Once a document matching the pattern for an ad-query-trigger rule was reached, directly or via redirect, further redirections will be examined. For those redirections, the query string of the URL will be examined. If it contains any of the strings provided as value to the option, ad attribution will be fully enabled and the origin of the matching URL will be stored as the ad landing origin for this tab.

The ad-query-trigger option requires a pattern that provides a domain name in the ad URL pattern. This means, the pattern should be host-anchored and the domain should be followed by ^,/ or ?

Once ad attribution is enabled for a specific tab and origin, that state is preserved so long as the tab navigates within this same origin. Navigating to a different origin will cause ad attribution to be disabled, but it’s state will be preserved for a half hour. Further navigations within the deadline extend it to a half hour. If the deadline passes, further navigations outside the original origin clear the state fully. Navigating back to the landing origin will re-enable ad attribution.

The ad attribution state is normally confined to the tab where it was enabled. However, a same-origin navigation to a new tab from a tab where it is enabled will preserve its state.

Ad attribution also always gets disabled seven days after being triggered.

3.Matching trackers when ad attribution is enabled

When ad attribution is enabled, it examines resources loaded on pages whose origin match the landing origin. In order to indicate which resources should be allowed for ad attribution, rules with the ad-attribution-tracker option are used.

@@||advertiser.example.org/track-click$ad-attribution-tracker=advertiser.example.com/&click-id-param=|advertiser.example.net/&ad_id=

The body of this rule matches the url of the resource itself, while the value of the ad-attribution-tracker option provides the context in which it should be allowed. The value of this option consists of a pairs of domain/query-fragment separated by |. The domain part is matched against the domain of the ad that was clicked (the ad itself, not its landing origin). The query-fragment is matched against the query fragment used to enable ad attribution. A pair matches if both components are a match. This rule matches if the resource url matches and any of the domain/query-fragment pair is a match. When a tracker is allowed this way, it bypasses blocking both in the ad blocker and the tracker blocker.

These rules are currently only available in the “Allow Ads from our Partners” list that is provided by Vivaldi. This is to avoid situations where they may be employed in malicious rules lists. You can examine our list to learn of which partner sites have ad attribution enabled and which trackers are allowed as a result here.

Pop-out Video, aka Picture-in-Picture, is a popular feature on desktop, but did you know it’s also available on Android and iOS? The main difference is that, on your mobile device, you can’t browse other tabs in Vivaldi while Pop-out Video is enabled, but you can use most other apps.

Enable Pop-out Video on iOS

1. While browsing with Vivaldi, find a video you want to watch.
2. Press play and enable full-screen view of the video.
3. Go to your phone’s home screen.

The video will continue playing in a small rectangle on your home screen. You can move the video by dragging it around and use the two-finger zoom gesture to change the size of the video.

Tap on the rectangle to see video controls. Pop-out Video includes controls for:

• Pausing the video.
• Fast forwarding or rewinding the video by 10 seconds.
• Closing the popped-out video.
• Returning to the main window.

Due to restrictions set by Google, the feature may unfortunately not work on YouTube’s website.

Ensuring Widget Performance

To make your widget performant, it’s important to deploy on-device caching using HTTP Caching. The stale-while-revalidate caching directive can help you achieve a compromise between an instantly-loading widget and up-to-date information.
