Browser uses too much memory
Modern browsers use RAM actively. Full-featured apps have replaced static pages on the internet. Let's say you have a music player open on one tab, a YouTube video on another tab, and an online editor on 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 preserved 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 to 1000 MB of RAM. If a page has complex Flash objects, the RAM utilization may grow to 1000 MB.
- preloading pages (click Search section, disable the Request page data in advance in order to load pages more quickly option);and in the
- Unused extensions.
- Flash plugin autorun.
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 plugins, is a separate process that won't affect other tabs and extensions in the event of a failure.
Browser freezes
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 stopped responding (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

- In the Cookies section, click Cookies and site data.
- Hover over the desired site and click the Remove link that appears to the right of the site name. All cookies of this page will be deleted.

. - Restart your network connection.
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 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.

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.
