We made some changes to our supported browsers documentation, making it easier to
find what you need. Supported browsers for Salesforce vary depending on whether you use
Salesforce Classic or Lightning Experience.
End of Support for Internet Explorer 11 in Lightning Experience
Extended Support for IE11 ends on December 31, 2020. IE11 users see a permanent banner in their Salesforce org, indicating that they’re on an unsupported browser. Customers using IE11 aren’t blocked from accessing Lightning Experience, but features aren’t guaranteed to work correctly. New features are supported and available only on modern browsers.
Supported Browsers for Einstein Analytics
Supported browsers for Einstein Analytics include those supported for Lightning Experience with the following differences: Analytics isn’t supported on Apple® Safari®, and Data Prep isn’t supported on Internet Explorer 11.
