After July 2021, the 2.3.x release line will no longer receive quality updates, or user guide updates. PHP 7.3 reaches end of support in December 2021 and Adobe Commerce 2.3.x reaches end of support in September 2022. We strongly recommend planning your upgrade now to Adobe Commerce 2.4.x and PHP 7.4.x to help maintain PCI compliance.

Browser Capabilities Detection

Like most websites and applications on the Internet, Magento requires that the visitor’s browser allow both cookies and JavaScript for full operations. However, occasionally a user’s browser is set to the highest privacy setting that prevents both cookies and JavaScript. Your store can be configured to test the capabilities of each visitor’s browser and display a notice if the settings need to be changed.

  • If the browser’s privacy settings disallow cookies, you can configure the system to automatically redirect them to the Enable Cookies page, which explains how to make the recommended settings with most browsers.
  • If the browser’s privacy settings disallow JavaScript, you can configure the system to display the following message above the header of every page.

For technical information, see Supported browsers in the developer documentation.

Configure browser capabilities detection

  1. On the Admin sidebar, go to Stores > Settings > Configuration.

  2. In the panel on the left under General, choose Web.

    • To display instructions that explain how to configure the browser to allow cookies, set Redirect to CMS-page if Cookies are Disabled to Yes.
