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

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.

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:

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.

Connection Failure error

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

Failures may occur due to the following:

Problems with how the site works

Try opening other sites in the browser. If you do not see the connection error, there was probably a failure on the side of the initial site, or the site's owner is running maintenance at the moment. Try going to the site again later. If the problem persists, contact the website's developers.

Problems with your internet provider

Contact your internet provider and ask if there have been any network failures or if they are conducting maintenance work.

Site blocked by antivirus or firewall

Check the list of blocked resources in your antivirus (Windows firewall). If you locate the page in the list, delete it.

Attention. Only delete a page if you are completely sure that it is safe, though. If the page contains malicious code, it can infect your computer or give hackers access to your personal information and electronic payments.
The browser was infected by a virus

Scan your computer using an antivirus or free utilities.

  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.
