Supported Browsers
------------------

.. note::

   The VOSS-4-UC administrator interface does not currently render equally
   well on all devices and window or screen sizes. It is regularly tested
   on standard display resolutions of 960×720, 1024×768 and 1280×960.
   There is currently no specific guaranteed support for smaller resolutions.



For this Release, testing was performed using the following browser versions.

Note that:

1. Older versions of each browser may also be compatible.
2. Specific older browser versions that are not compatible with safety and security options such as with "X-Content-Type-Options: nosniff" headers, are not compatible.

Internet Explorer 10 and 11 running on Windows 7 require adjustments to the browser's SSL/TLS
settings to work:

1. In the browser, choose **Tools > Internet Options**.
2. Click the **Advanced** tab.
3. Scroll to the **Security** heading.

   * For IE 10, locate and select the **Use TLS 1.0** check box, and clear the 
     **Use SSL3** check box if selected.
   * For IE 11, locate and select the **Use TLS 1.0** and **Use TLS 1.2** check boxes.

4. Click **Apply**, then click **OK**.

If TSL1.2 does not work, select the **Use SSL3** and **Use TLS 1.2** check boxes
on both IE 10 and IE 11.
