Browser Support Considerations for Lightning Components

Browser support varies across different Salesforce products and experiences. Use this browser support information as you build with Lightning components.
Salesforce Classic available in: All Editions

Lightning Experience is available in: Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions

The following tables provide high-level minimum browser versions for various Salesforce features. There are additional requirements and recommended settings for all browsers, and a number of considerations that apply to specific browsers. See the browser compatibility details in Salesforce Help.

Lightning Experience and Lightning-Based Features

The following table describes minimum browser version requirements for using Lightning components within various features that are built with our next-generation user interface platform.

1 Locker Service is disabled for IE11. We recommend using supported browsers other than IE11 for enhanced security.

Support for Internet Explorer 11 to access Lightning Experience is retiring beginning in Summer ’16.

  • You can continue to use IE11 to access Lightning Experience until December 16, 2017.
  • If you opt in to Extended Support for IE11, you can continue to use IE11 to access Lightning Experience and Communities until December 31, 2020.
  • IE11 has significant performance issues in Lightning Experience.
  • It is strongly recommended that you do not use Internet Explorer 11 with Community Builder.
  • This change doesn’t impact Salesforce Classic.
