Solving problems

If Yandex.Browser doesn't launch 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 happens during the following steps:

• What happens when you try to open Yandex.Browser (for example, do you get an error message? does the browser window not 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 have you had problems opening Yandex.Browser?

If possible, include a screenshot.

Try temporarily disabling all extensions, Turbo mode, and 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 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, webpages don't load immediately on the user's computer, but are rather sent to Yandex's server for compression. This usually speeds up the browser significantly. However, if the route from the Yandex server to the user's computer is very long, Turbo pages may take longer to load than they would if the mode was disabled.

Check whether your browser speeds up after you disable Turbo:

1. Tap  → 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. In the Delete the following list, select the time range you want to delete cache for.
3. Check the Cached files option.
4. Turn off all the other options (if you only want to delete the browser cache).
5. Click Clear browsing data.

Clear history

1. Click   → History → History, and then Clear history in the top 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. Check the Browsing history option.
4. If necessary, deselect all other options.
5. Click Clear browsing data.

Clear cookies

1. Click   → Advanced → Clear history.
2. In the Delete the following list, select the time range you want to delete cookies from.
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 plug-ins, 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

Various network restrictions may make it difficult to access a site. For example, it 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 actually works. If you only have problems accessing the site on your computer, we recommend contacting your system administrator or the customer service department of your internet provider.

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 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 problem doesn't occur in Incognito mode, disable your extensions one at a time to figure out which one is blocking the page from displaying.

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 see this error when you open a page, try to solve the problem in one of these ways:

Delete cookies

1. Click   → Advanced → Clear history.
2. In the Delete the following list, select the time range you want to delete cookies from.
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. In the Delete the following list, select the time range you want to delete cache for.
3. Check the Cached files option.
4. Turn off all the other options (if you only want to delete 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.
2. In the window that opens, enter cmd to launch the shell.
3. Enter ipconfig/flushdns in the shell.
4. Restart your network connection.

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

Try refreshing the page, clearing the browser cache and cookies, or disabling Turbo mode, utilities and browser extensions that may be causing the problem.

Disable utilities

The most frequent causes for incorrect site rendering are the use of a proxy server or an additional firewall (in addition to the standard Windows firewall). Temporarily disable them to find out if they are causing the webpage rendering problems. We do not recommend using utilities that break the page rendering.

Check browser extensions

1. Temporarily disable all extensions:  → Extensions.
2. If this solves your problem, go through your extensions 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. Clear your cache so that the browser doesn't load a copy of the page that was incorrectly rendered earlier.

Refresh page

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

Delete cookies

1. Click   → Advanced → Clear history.
2. In the Delete the following list, select the time range you want to delete cookies from.
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

1. Tap  → Settings.
2. In the Turbo section, click Disable.

Clear the browser cache

1. Click   → Advanced → Clear history.
2. In the Delete the following list, select the time range you want to delete cache for.
3. Check the Cached files option.
4. Turn off all the other options (if you only want to delete the browser cache).
5. Click Clear browsing data.

There are several reasons why images or photos may not display:

Images blocked by extension

Some extensions (such as ad blockers) limit the display of page contents, 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.
5. Refresh the page to make sure the problem resolves.

Images blocked in browser settings

1. Turn off images:  → Settings → Show advanced settings → Privacy → Content settings → Images.
