The browser, Mozilla Firefox, has changed certain things behind the scenes. These changes don't allow for you to navigate through our store without opening another tab first. To continue shopping, you must click on the small red "x" at the tab to close that tab and go on to another product. You have to do this each time you need to "continue shopping". Redd-Eye Brand apologizes for this extra step and for any inconvenience it may have caused but are not able to rectify this with this specific browser. Internet Explorer customers aren't experiencing the same problem. (further explanation: we are keeping our web site set to accommodate the average customer since most customers using Mozilla Firefox recognize the additional tab that appears). Thank you for your patience and continued support.
