Subscription Edition SharePoint in Microsoft 365
SharePoint Server Subscription Edition supports several commonly used web browsers, such as 
Microsoft Edge, 
Google Chrome, 
Mozilla Firefox, 
Apple Safari, and 
Internet Explorer. However, certain web browsers can cause SharePoint Server Subscription Edition functionality to be downgraded, limited, or available only through alternative steps.
Note
Internet Explorer 11 and Edge IE compatibility mode are supported only in the SharePoint Central Administration site.
Internet Explorer 11 and Edge IE compatibility mode are not supported in Team sites, OneDrive personal sites, or any other types of SharePoint content sites. Microsoft recommends exploring Microsoft Edge as the replacement for Internet Explorer 11.
As you plan your deployment of SharePoint Server Subscription Edition, we recommend that you review the browsers used in your organization to guarantee optimal performance with SharePoint Server Subscription Edition.

Browser details
Review the details of the web browser that you have or plan to use in your organization to ensure that the web browser works with SharePoint Server Subscription Edition, and according to your business needs.
Internet Explorer and older functionalities
Note
Some older SharePoint functionalities that rely on NPAPI or ActiveX will not work on browsers other than Internet Explorer. Since Internet Explorer 11 is no longer supported in all types of SharePoint Sites except Central Administration site, these old functionalities are deprecated as well. Although these functionalities still exist in SharePoint Server Subscription Edition, we recommend not to rely on them anymore.
Using ActiveX controls in SharePoint Server
Some functionalities in SharePoint Server require ActiveX controls. This imposes limitations on browsers that don't support ActiveX. Currently only 32-bit versions of Internet Explorer support this functionality. Since Internet Explorer 11 isn't supported in all types of SharePoint sites except Central Administration site, all supported browsers (including Microsoft Edge) have the following limitations.
| Plugin name | DLL file name | What it does | Known limitations | |
|---|---|---|---|---|
| Digital Signature |

Digital signing takes place in both the InfoPath client and on the InfoPath Forms Services server. Ensure that the following conditions exist: Forms that are signed on the client can be verified on the server. Forms that are signed on the server can be verified on the client. |
An inability to verify a form produces an error that states that the form can't be signed. |
