Recommendations and Requirements for All Browsers

The following recommendations and requirements apply for all browsers, whether you’re using Salesforce Classic or Lightning Experience.

Note Salesforce doesn’t support non-browser applications that embed WebView or similar controls to render content for Salesforce Classic, or Lightning Experience. Examples of approaches that embed this type of control include Salesforce Mobile SDK, Microsoft’s WebBrowser Control, Electron’s embedded Chromium browser, iOS’s UIWebView and WKWebView, and Android’s WebView.

• For all browsers, enable JavaScript, cookies, and TLS 1.2 or 1.3. Salesforce no longer supports TLS versions TLS 1.1 and 1.0.

  If cookies aren’t enabled, certain preferences managed via checkboxes don't appear, such as when using the email composer in Lightning Experience.

• Some features use iframes to work in Lightning Experience, so you must have the appropriate browser security settings for iframes to load correctly. Follow your browser’s instructions to enable working with iframes and third-party cookies. For example: In Internet Explorer, set the Launching programs and files in an IFRAME security setting to Enable or Prompt. In Safari and Chrome, we recommend changing your privacy settings to allow all cookies.

• The minimum screen resolution required to support all Salesforce features is 1024 x 768. Lower screen resolutions don’t always properly display Salesforce features such as Report Builder and Page Layout Editor. The Three Regions template and the pinned region templates are designed with Lightning console apps in mind. They feature a main region and two sidebars with fixed proportional widths. The main region is 50%, and the side region widths are each 25%. Three-region templates require more screen width to display correctly. Three-region templates can display incorrectly on certain devices or monitors with low resolutions.

  

  Note Even if your monitor settings meet the minimum screen resolution, resizing a Salesforce browser window to below the minimum resolution can cause display issues.
• 4K displays can cause issues with components that are programmed with screen percentages in mind. Resize and then refresh your window to solve most issues.
• Moving a window from a 4K display to a 1080p or 1440p display can cause unwanted behavior or resizing issues.
• For Mac OS users on Apple Safari or Chrome, make sure the system setting Show scroll bars is set to Always.

• Some third-party browser plug-ins and extensions can interfere with the functionality of Chatter. If you experience malfunctions or inconsistent behavior with Chatter, disable the browser's plug-ins and extensions and try again.

  Other products and features may also be affected by third-party plug-ins and extensions.

Some features in Salesforce—and some desktop clients, toolkits, and adapters—have their own browser requirements. For example, Internet Explorer is the only supported browser for:

• Standard mail merge (Salesforce Classic)
• Connect Offline

For the best experience on machines with 8 GB of RAM in the Salesforce Console, use Chrome.
