What is browser ubiquity?
The term "browser ubiquity" describes an SSL certificate's browser compatibility — i.e., the extent to which the Certification Authority's (CA) root certificate is included in the Web browsers on the market. In other words: If the root certificate of the CA is present in the "Trusted Root Certificates" store of the browser, the SSL certificates issued by the CA are compatible with that browser. The more browsers and browser versions supported, the higher the level of browser ubiquity, and hence, the more versatile the certificate is. Thus, high browser ubiquity means that most existing browsers recognize a given certificate, and that secure transactions thus can take place on those browsers. Most SSL certificate services support all major browsers.
Our root certificate — the Valicert Class 2 Policy Validation Authority — is installed in the following browser versions:
- Internet Explorer 5.01 and higher
- AOL 5 and higher o Netscape 4.7 and higher
- Opera 7.5 and higher
- Safari on Mac OS X 10.3.4 and higher
- Mozilla (all versions)
- Firefox (all versions)
- Konqueror (all versions)
- Palm OS 6.1 and higher (also Treo 650)
- BlackBerry OS 4.1 and higher
- Sony Playstation Portable 2.5 and higher
- Microsoft Windows Mobile 2005 AKU 2 and higher
- Sun Java Runtime (JRE) 1.4.2_07 and higher and 1.5.0_02 and higher
- ACCESS NetFront 3.3 and higher
- AT&T WAP Gateways (any AT&T phone which uses WAP version 1.X for Web browsing)
- Many Nokia devices manufactured in 2007 and later
- Apple iPhone (both EDGE and 3G)
That equals 99% total browser ubiquity.
Users of older browser versions may receive a warning that the root certificate is not trusted. When presented with the warning those users can simply install the root certificate. To do so, click "View Certificate." Then, when the certificate is displayed, click "Install Certificate." Alternatively, users of older browsers may download and install the root certificate directly from the Repository.
