Vivaldi is a freeware web browser that supports multiple platforms and is based on Chromium. However, several users reported that Vivaldi is slow on their devices.

For instance, users report a delay when opening or switching to another tab.

Thankfully, there are a few workarounds that you can perform to speed up the browser’s performance. But, before we head to that, let’s first find out why Vivaldi is running slow.

Why is Vivaldi running so slow?

Like any other browser, a few issues could lead to Vivaldi lagging on your system. The most common is having multiple tabs open at once. Though you can have several of them open at a given point, it would slow Vivaldi’s performance.

Then comes the extensions. These are too known to affect the functioning of the browser. Here, it’s not necessarily the quantity but also the quality that is critical. A single problematic or conflicting extension can considerably slow down Vivaldi.

Besides, certain browser settings, having a custom theme, or running an outdated version of Vivaldi can cause it to slow down. Sometimes, Vivaldi might be slow after an update, in which case you will have to wait for the next version to be released.

Which browser is faster than Vivaldi?

Several browsers are faster than Vivaldi, be it Opera, Chrome, or Firefox. But the latter two generally have performance-related issues. For instance, Chrome is known to consume high CPU, while Firefox often fails to respond.

Considering these aspects, we recommend going with Opera, but you can also try the other two. Though Opera does offer a built-in VPN and ad blocker, the latter is known to fix the slow loading of pages, a common problem with Vivaldi.

Quick Tip:
Use a lighter, more stable browser. We recommend Opera because it’s up to date and uses very few system resources.

The browser removes the need to load unnecessary ads with its integrated, free adblocker. It also has a battery-saving mode that can also contribute to better overall performance.


If you’re looking for a fast and customizable browser with minimum impact on your OS, Opera is the answer.

How can I fix Vivaldi if it’s slow?

1. Close the settings page

If you prefer to keep using Vivaldi, then start by tweaking some settings.

One reason for the browser’s slow pace can be an opened settings page (vivaldi://settings/all/). Normally, your first stop is in the settings tab, as you might want to make some changes to the browser before using it.

Once you finish customizing the browser, make sure to close the settings page. Otherwise, Vivaldi will delay other browser activities. Once done, check if Vivaldi’s slow startup problem is fixed. If not, head to the next method.

2. Modify or disable browser functions

  1. Paste the following path in the address bar, and hit Enter:vivaldi://settings/startup/
  2. Set the Startup with setting to Specific pages without assigning a URL to the field.Specific pages to fix vivaldi slow
  3. Now, enable the Lazy Load Restored Tabs option if you previously configured the browser to load the last session upon startup.Lazy load restored tabs to fix vivaldi slow
  4. Now, paste the following path and hit Enter:vivaldi://settings/appearance/
  5. Uncheck the Use Animation and Use Buttons in Range Controls boxes.Checkboxes

  7. Now, uncheck the following options under the Tab Options, Show Popup Thumbnails, Show Tab Thumbnails, Detect Page Title Notifications, and Use Unread Indicators.Disable tab option to fix slow vivaldi

If you cannot live without all of the features of the browser, do not perform the mentioned changes.

However, you may choose to do away with some to increase the speed of Vivaldi. Extensions can also slow down your browser, so you may want to disable some of them, as mentioned.

Does Vivaldi use a lot of RAM?

Vivaldi is a lightweight browser and consumes lower resources compared to Chrome or Firefox. This is one of the major reasons why most users go for it, in addition to the several beneficial features offered by Vivaldi.

But, there have been cases where users reported encountering high RAM or high CPU usage with Vivaldi, but that’s generally due to an issue. In case you are unable to fix things, there is always the option to switch to a more reliable browser like Opera.

That’s all about the issue and how you can speed up Vivaldi on your device. By the time you reach this part, the problem should be long gone. Also, find out what to do if Vivaldi is not loading pages.
