Browser compatibility plays a vital role when you secure your website with an SSL certificate. If the browser does not know the root certificate of your SSL certificate, it will show a security warning; hence, a verified communication cannot be established. As a result, the customer will be bounced from the website and result in lower business transactions. The more browsers recognize the root certificate, the more your website will be visible in other browsers.
Currently, most of the popular certificate authorities have correlation with browser vendors, so that their root certificates can be identified by major popular browsers like Firefox, Internet explorer, Safari, Opera, Netscape. This is the reason, one should always choose SSL certificate that does not file such security warnings. SSL certificates from reputed certificate authorities like Symantec, GeoTrust, Thawte, RapidSSL, Globalsign, Comodo, AlphaSSL are compatible with over 99%+ of desktop and mobile browsers.
