Solving 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 beta version of Yandex Browser, download the file from browser.yandex.com/beta.

If this doesn't help, use the Feedback form to report the issue to technical support.

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.

Try temporarily disabling all extensions, Turbo mode and Alice voice activation. Also clear your cache, history, and cookies.

Turn off 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.

Disable Turbo mode

In Turbo mode, site pages aren't immediately downloaded to the user's computer. They are first sent to the Yandex server and compressed there. This usually speeds up the browser significantly. However, if the route from the Yandex server to the user's computer is very long, the page might take longer to load in the Turbo mode than without it.

Check whether turning off Turbo speeds up the browser:

1. Click  → Settings.
2. At the bottom of the Settings page, click Show advanced settings.
3. In the Turbo section, set the option to Off.

Clear the cache

1. Click  → Advanced → Clear history.
2. Under Delete the following, select the time range you want to delete the cached data for.
3. Select the Cached files option.
4. Disable all the other options (if you only want to clear the browser cache).
5. Click Clear browsing data.

Clear history

1. Click  → History → History, and then Clear history in the upper-right corner of the tab.
2. In the Clear browsing data window, set the time period that you want to delete the history for.
3. Select the Browsing history option.
4. If necessary, deselect all other options.
5. Click Clear browsing data.

Clear cookies

1. Click  → Advanced → Clear history.

   Tip. You can open the Clear history window by pressing Keyboard shortcuts Ctrl + Shift + Del (on Windows) or Shift + ⌘ + Backspace (on macOS).
2. Under Delete the following, select the time range you want to delete cookies for.
3. Select Cookies and other website and plugin data (disable all the other options if you only want to delete cookies).
4. Click Clear browsing data.

If you couldn't fix the problem yourself, send a message to the Support service in the Feedback form. Describe the situation in as much detail as possible.

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. In the right part of the SmartBox, click any Protect toolbar icon.
2. In the Permissions section, click cookie files for this site.
3. In the Cookies in use window, select a cookie and click Remove. Delete all cookies
4. Click Close.

Check whether the problem persists.

Browser extensions block a webpage from loading

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.

Turbo mode

Some sites don't display in Turbo mode. To disable Turbo mode:

1. Click  → Extensions.
2. Select the Tools section.
3. Turn off Turbo.

Browser problems

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:

Delete cookies

1. Click  → Advanced → Clear history.

   Tip. You can open the Clear history window by pressing Keyboard shortcuts Ctrl + Shift + Del (on Windows) or Shift + ⌘ + Backspace (on macOS).
2. Under Delete the following, select the time range you want to delete cookies for.
3. Select Cookies and other website and plugin data (disable all the other options if you only want to delete cookies).
4. Click Clear browsing data.

Clear your cache

1. Click  → Advanced → Clear history.
2. Under Delete the following, select the time range you want to delete the cached data for.
3. Select the Cached files option.
4. Disable all the other options (if you only want to clear the browser cache).
5. Click Clear browsing data.

Reset your DNS settings

1. Press Windows + R or enter “Run” in the Windows search bar and select an application from the list.

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 Turbo mode, 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 (on Windows) or ⌘ + Shift + R (on macOS).

Delete cookies

1. Click  → Advanced → Clear history.

   Tip. You can open the Clear history window by pressing Keyboard shortcuts Ctrl + Shift + Del (on Windows) or Shift + ⌘ + Backspace (on macOS).
2. Under Delete the following, select the time range you want to delete cookies for.
3. Select Cookies and other website and plugin data (disable all the other options if you only want to delete cookies).
4. Click Clear browsing data.

Turn off Turbo mode

Images are blocked by an extension

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

1. Temporarily disable all extensions:  → Extensions.
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.
4. Clear your cache so that the browser doesn't load an incorrect copy of the page that was rendered earlier and contains blocked images.

Images are blocked in the browser settings
