Solving problems

The browser doesn't launch

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.tr. If you are using the beta version of Yandex.Browser, download the file from browser.yandex.com.tr/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.

Browser is slow

Try temporarily disabling all extensions, Turbo mode, and also clear your cache, history, and cookies.

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.

The browser uses too much memory

Modern browsers actively use RAM. Full-fledged web apps have replaced static pages on the internet. Say that you have a music player open on one tab, a YouTube video on another, and you are working in an online editor in a third. In order to make it possible to quickly navigate between tabs, data associated with them must be stored in your RAM.

Yandex.Browser may use more memory in comparison with other browsers due to the following:
  • Multi-processor architecture. Every browser window is a separate process that takes up additional memory. This increases the stability; if something malfunctions on one tab, the other ones will continue working and you won't lose any data.
  • Restart. The browser tries to determine which link you will click and load the page data without waiting for you to click.
  • Many extensions. Extensions make it easier to work in the browser, but each one takes up RAM.

On average, Yandex.Browser consumes from 300 to 1000 MB of RAM when you have several tabs open. If a page has complex Flash objects, memory consumption may exceed 1000 MB.

To decrease the required RAM, try disabling the following:

Yandex.Browser launches a lot of processes

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.

The browser freezes or pages won't open

If your browser freezes, contact our support staff using the feedback form. Describe your situation in as much detail as possible:

  • What actions cause the browser to freeze?
  • Describe what happened before the browser froze (for example, did you reinstall the browser or update or install programs or extensions?)

If the browser is slow opening pages, then clarify the following in your message:

  • Does the problem occur with all webpages or only certain ones (if so, which ones?)
  • Add a link to the net-export log. You will need to take screenshots of this log (as explained in the instructions) and upload them to any cloud storage of your choice.

If you have problems opening pages, include the error text in your message.

Site doesn't open

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

DNS Error

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

Proxy server error

If you see this error, it means the internet connection in the browser is set to use a proxy server. If your network doesn't use a proxy server, turn off this option.

  1. Tap  → Settings.
  2. At the bottom of the Settings page, click Show advanced settings.
  3. In the Network section, click Change proxy settings.
  4. In the window that opens, go to the Connections tab and click Network settings.
  5. In the window that opens, deselect the option Use a proxy server for your LAN.

Connection Failure error

A “Connection failure” error means that the browser could not retrieve a webpage.

Failures may occur due to the following:

Page content displays incorrectly

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.

The downloads toolbar, suggestions or dialog boxes are not displayed

Note. This is only a problem for Windows 10 users.

Errors may occur with some integrated video cards after you update Yandex.Browser:

  • Suggestions disappear.
  • Downloaded files no longer display in the downloads toolbar.
  • The browser doesn’t respond when you try to use it for the first time after an update. However, the Enter key does work. When you press it, a Windows dialog box opens and prompts you to select your default browser.

If you get one of these errors, deselect the Hardware acceleration option in the browser:

  1. Tap  → Settings.
  2. At the bottom of the Settings page, click Show advanced settings.
  3. In the System section, deselect the option Use hardware acceleration if possible.
  4. Restart the browser to apply these changes.

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

Images are not displayed

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

Images don't display correctly

If the image on the page doesn't display correctly (for example, if the image opacity was not saved in a PNG image), try disabling image optimization:

  1. Tap  → Settings.
  2. At the bottom of the Settings page, click Show advanced settings.
  3. In the System section, disable the Optimize images to save memory option.
  4. Restart the browser to apply these changes.

The browser ruins the color rendition

Check your monitor's color profile settings

  1. Enter browser://flags/ in SmartBox.
  2. Find the Force color profile option and change its value.
  3. Relaunch the browser and see what results you get.
