Solving common problems

If Yandex Browser doesn't start or you see the "The application has failed to start because its side-by-side configuration is incorrect" error, try installing the latest browser version. You can download the installation file from browser.yandex.com. If you are using the Yandex Browser beta version, download the file from browser.yandex.com/beta.

If this didn't help, use the Feedback form to report the issue to the support team.

Describe what is happening, step by step:

• What happens when you try to open Yandex Browser (for example, you get an error message or the browser window doesn't open correctly).
• What happened before this issue started occurring (for example, did you update your browser or OS? did you install a program or extension?).
• How long you have been experiencing problems opening Yandex Browser.

If possible, attach a screenshot.

You don't need to worry if there are a lot of processes running. All browsers based on the Chromium engine work like this. Every browser window, as well as some extensions and plugins, is a separate process that won't affect other tabs and extensions in the event of a failure.

There are a few reasons why a site may not open:

Network constraints

Certain restrictions in your network can also obstruct site access. Those might be caused by software (antivirus programs, firewalls, or viruses), or network settings on the provider side (such as proxy servers).

Check whether you can access the site on another computer from a different network to make sure that the site works. If the site fails on your computer only, we recommend contacting your system administrator or your provider's support.

There are a lot of temporary files

Webpages may not load completely if you have a lot of temporary files. Follow these instructions to delete all cookies for that page:

1. Tap  → Settings.
2. Open Websites.
3. At the bottom of the page, click Advanced site settings.
4. In the Cookies section, click Cookies and site data.
5. Hover over the desired site and click the Remove link that appears to the right of the site name. All cookies of this page will be deleted.

Check whether the problem persists.

Website blocks extensions

To check whether extensions are blocking a page from displaying, open the site in Incognito mode. If the Incognito mode does not reproduce the problem, try to find an extension that blocks page loading.

1. Temporarily disable all extensions:  → Extensions.
2. If the page has loaded, try going through your extensions one at a time to find the one that is blocking them.
3. Disable the problematic extension. You may want to let the developers know about the problem.
4. Clear your cache so that the browser doesn't load a copy of the page that was saved earlier.
5. Refresh the page to make sure the problem has been resolved.

Incorrect DNS settings

1. Open the Windows shell. Press Windows + R on the keyboard or type “Run” in the search bar. In the dialog box that opens, enter cmd using your keyboard.
2. Enter ipconfig /flushdns.
3. Restart your network connection.

Other problems with the browser

If a site opens in every browser other than Yandex Browser, send a message to our support staff using the feedback form. Describe the situation in detail, and attach a screenshot if possible.

If you see this error message when you open a page, try to solve the problem using one of these methods:

Some website features may stop working after cookies have been blocked. For example, notifications you previously enabled in the browser or the verification code window may not pop up anymore. If you see the icon on the right side of SmartBox, it means that you blocked cookies on that page.

If you see the sign:

1. Tap  → Settings.
2. Open Websites.
3. At the bottom of the page, click Advanced site settings.
4. In the Cookies section, select Allowed.
5. Turn off the Block third-party data and files option.
6. Click Sites advanced settings.
7. Check whether the Only for session or Not allowed lists contain the problematic site. If a site is in the list, hover over it and click the Allow link.

Webpages might display incorrectly. For example, garbled characters may display instead of letters or the page formatting may be broken.

Try the following: refresh the page; delete your browser cache and cookies ; disable utilities, and browser extensions that may be causing the problem.

Disable utilities

The most frequent reason for incorrect site display is using a proxy server or an additional firewall (in addition to the standard Windows firewall). Temporarily disable them to find out if they affect the display of site pages. We do not recommend using utilities that cause display errors.

Check your browser extensions

1. Temporarily disable all extensions:  → Extensions.
2. If this solves your problem, go through your extensions and turn them back on until you find the one that caused the problem.
3. Disable the problematic extension. You may want to let the developers know about the problem.
4. Delete your cache so that the browser doesn't load an incorrect copy of the page loaded earlier.

Refresh page

1. Open the page with the formatting problems.
2. Press F5 (in Windows) or ⌘ + Shift + R (in macOS).

Delete cookies

1. Click  → Advanced → Clear history.

   Tip. You can open the Clear history window by pressing the following keys: Ctrl + Shift + Del (in Windows) or Shift + ⌘ + Backspace (in macOS).

3. Select Cookies and other website and plugin data (disable all the other options if you only want to delete cookies).

Clear your cache

Images are blocked by an extension

Some extensions (such as ad blockers) restrict the display of page content, including videos and images.

2. If images appeared, try going through your extensions one at a time to find the one that is blocking them.
3. Disable the problematic extension. You may want to let the developers know about the problem.
