Solving common problems
This section provides solutions to the most common problems that occur when using Yandex Browser.
Installation and launching |
Installation and launching |
If Yandex Browser doesn't start or you see the error "The application has failed to start because its side-by-side configuration is incorrect," try installing the latest browser version. Download the installation file from browser.yandex.com/ .
If this doesn't help, write to us.
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 Yandex Browser window doesn't open correctly).
- What happened before this issue started occurring (for example, did you update Yandex 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.
The browser may freeze if there's less than 600 MB of free disk space. Free up disk space.
If this doesn't help, contact support using the form.
- Describe what actions cause Yandex Browser to freeze.
- 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.
- In your user profile, close all the tabs, clear the cache, and restart the browser.
If this doesn't help, try creating a new user profile and repeat the situation in it.
Attention. Don't delete your old profile when creating a new one since it contains your data (for example, bookmarks, passwords, and so on).After that, open Yandex Browser via the shortcut of your new profile on the desktop and check whether it starts faster. If everything works correctly in the new profile, you can continue using it and transfer all your personal data from the old profile by syncing (enable syncing in the new profile under the same username as in the old one).
Don't delete your old profile until you're sure that everything works correctly in the new one after the transfer.
If the situation repeats after you transfer the settings, this may mean that an extension isn't working correctly. Turn off the extension that is causing problems:
- Click Ctrl+Shift+Q.and turn off all the extensions. Restart Yandex Browser using the keyboard shortcut
- Clear your cache so that the browser doesn't load a copy of the page that was saved earlier.
- If this solves your problem, go through your extensions and turn them back on until you find the one that causes the problem. Restart Yandex Browser every time.
- Disable this extension. You may want to let the developers know about the problem.
Memory and performance |
Memory and performance |
Modern browsers use RAM actively. Full-featured apps have replaced static pages on the internet. Let's say you have a music player open in one tab, a YouTube video in another tab, and an online editor in a third. In order for you to switch between tabs quickly, your data has to be stored in RAM.
- Multiprocessor architecture. Each browser window is a separate process that requires additional memory. The multi-processor architecture improves stability. If one of the tabs fails, the other tabs are saved and you will not lose your data.
- Pre-loading. The browser tries to figure out what link you may click, and loads the page data in advance.
- Large number of extensions. Extensions make browsing easier, but each of them requires RAM.
On average, with several tabs open, Yandex Browser consumes from 300 MB to 1000 MB of RAM.
- Preload pages (click Search and deselect Request page data in advance to load pages more quickly)., go to
- Unused extensions.
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.
Check all extensions and clear your cache, history, and cookies.
- Click Ctrl+Shift+Q.and turn off all the extensions. Restart Yandex Browser using the keyboard shortcut
- Clear your cache so that the browser doesn't load a copy of the page that was saved earlier.
- If this solves your problem, go through your extensions and turn them back on until you find the one that causes the problem. Restart Yandex Browser every time.
- Disable this extension. You may want to let the developers know about the problem.
- Click press Ctrl + Shift + Del (in Windows and Linux) or Shift + ⌘ + Backspace (in macOS). or
- Under Clear history, select the time period that you want to delete the cache for.
- Select the cached files option.
- Deselect all other options (if you want to clear only the Yandex Browser cache).
- Click Clear.
- Click.
- In the lower-left corner, click Clear history.
- In the Clear history window, set the period.
- Select Views.
- If necessary, deselect all other options.
- Click Clear.
- Click press Ctrl + Shift + Del (in Windows and Linux) or Shift + ⌘ + Backspace (in macOS). or
- Under Clear history, select the time period that you want to delete the cookies for.
- Select Cookies and other site data and plugins (deselect all other options if you want to delete only cookies).
- Click Clear.
If this doesn't fix the problem, write to us and describe the situation in as much detail as possible.

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.
Webpages may not load completely if you have a lot of temporary files. Follow these instructions to delete all cookies for that page:
Check whether the problem persists.
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.
If a site opens in all browsers except Yandex Browser, contact support. Describe the situation in detail, and attach a screenshot if possible.
If you see the message "Cannot establish a secure connection" with the error ERR_CERT_DATE_INVALID when opening the site, or the error is displayed instead of part of the site, this may mean that the IdenTrust DST Root CA X3 root certificate in the operating system expired.
Yandex Browser uses root certificates installed in the operating system, so you need to solve the problem with the certificate in the system:
- Download the update package for 32-bit Windows 7 or 64-bit Windows 7.
- Run the update package and wait for it to install.
- Restart your computer and open the website.
- If the site doesn't open, update the certificate manually:
- Download the archive.
- Unpack it anywhere that is convenient.
- Open the
certificate update
folder. - Right-click the
update.bat
file and select Run as Administrator. - After performing the commands, restart your computer and open the site.

certificate update
folder. - Right-click the
update.bat
file and select Run as Administrator. - After performing the commands, restart your computer and open the site.
If you cannot establish a secure connection to Yandex services due to the ERR_CERT_AUTHORITY_INVALID error, it means that the certificate is missing from the operating system. Update Windows (
). If this didn't help, try downloading and importing the certificates manually:- Downloading the certificates to your computer using the following links:

- Open the Windows Control panel.
- Click Folder Options (in Windows 10, click File Explorer Options).
- On the View tab, clear the Hide extensions for registered file types option.
- Click Apply.
- Open the Certum CA certificate in Notepad and save it after removing the .txt extension to get the CA.pem file.
- Open the Certum Trusted Network CA certificate in Notepad and save it after removing the .txt extension to get the CTNCA.pem file.
- Import certificates by going through the following steps for each certificate:
- Open the Windows shell. Press Windows + R or type “Run” in the search bar. In the dialog box that opens, enter
certmgr.msc
. - Open the Trusted root certification authorities folder and then the Certificates folder.
- Click. The Certificate Import Wizard starts.

Try opening other sites in Yandex 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.
Contact your internet provider and ask if there have been any network failures or if they are conducting maintenance work.
Check the list of blocked resources in your antivirus (Windows firewall). If you locate the page in the list, delete it.
Scan your computer using an antivirus or free utilities.
Yandex Browser used Turbo mode to speed up access to various sites, but it only worked with the HTTP protocol. Since there aren't many sites like that left, we turned off Turbo mode in Yandex Browser and removed it from settings. We introduced other mechanisms to keep Yandex Browser fast without any special modes and will continue working to make it even faster.
You can't clear the SSL cache using Yandex Browser tools because it uses the system certificate store.
To clear the SSL cache, use the Windows settings:
- Open the Control Panel.
- Choose Browser properties. If you have the category view mode enabled, choose .
- On the Content tab, click Clear SSL.
