Coupon Creator supports the current versions of all major modern browsers: Chrome, Firefox, Safari, and Edge.
These browsers update themselves automatically, so keeping yours current is all you need to do. Coupons, the print view, and the admin controls are built and tested against today's web standards for HTML, CSS, and JavaScript, which these browsers all support.
Very old browsers, including any version of Internet Explorer, are not supported. Microsoft has retired Internet Explorer, and it does not support the modern web standards the plugin relies on, so coupons may not display or print correctly there. Visitors on those browsers should switch to a current browser.
If a coupon looks wrong in a supported, up-to-date browser, it is usually a theme or plugin conflict rather than a browser limitation. See Troubleshooting Plugin and Theme Conflicts.
