Browser Support Policy

To better meet your needs, UL PureSafety uses statistical data from web visitors and registered users, rather than generic industry data, to identify the browsers used by our target audience. We regularly review this data to determine which browsers to support.

UL PureSafety validates against and supports the following browsers:

1. • Chrome (latest version)
2. • Internet Explorer (10, 11)
3. • Microsoft Edge
4. • Firefox (latest version)
5. • Safari (mobile only)

Other browsers might also work, but we do not attempt to resolve problems with browser/platform combinations other than those listed above. Browsers that have been developed to comply with the W3C guidelines and specifications, including mobile browsers, should operate successfully.
