<script type="text/javascript">
    if (navigator.userAgent.indexOf('Firefox') !=-1)
    {
        // Using Firefo
window.location = "http://mywebsite.com/firefoxwebpage"
 
    }</script>

Similar to Firefox, The user agent string – available in navigator.userAgent – will always include the text “Chrome”. We can then check for this in a simple indexOf:

<script type="text/javascript">
    if (navigator.userAgent.indexOf('Chrome') !=-1)
    {
        // Using Chrome
window.location = "http://mywebsite.com/chromewebpage"
    }
