We are pleased to announce a major upgrade to Rigor’s Real Browser checks: our Real Browser Check V3 Platform (RBCv3). RBCv3 updates the underlying browser and infrastructure that Rigor uses to conduct synthetic browser tests. With RBCv3, Rigor now uses the latest version of Firefox ESR, improving the accuracy and consistency of our measures. In addition to more precise measurements, RBCv3 adds three new features.

1. Measuring Websites Over HTTP/2

With RBCv3, Rigor now supports testing how websites load over HTTP/2. HTTP/2 can provide a huge boost in website performance and user experience by more efficiently using the browser’s underlying network connection. Now customers can measure and monitor those HTTP/2 performance gains with Rigor.

RBCv3 mirrors the browser’s behavior. It will automatically use HTTP2 for websites that support it and that are served of SSL/TLS.

2. Verifying SSL/TLS Certificates

Rigor has always been able to monitor and alert on a number of failure conditions, such as a network failure or if a page takes too long to load. With RBCv3, we have added the ability to fail a Real Browser check if the site has an invalid or expired SSL/TLS certificate.

The increased adoption of SSL/TLS for sites in 2016 provides greater security and privacy for users and, as a requirement to use HTTP/2, paves the way to better web performance. However, the downside is that organizations now must manage server certificates that prove the identity of their sites, as well as those certificates are kept up-to-date. RBCv3’s ability to notify users of failing certificates ensures that organizations can support secured connections to their sites.

3. Testing With Larger Viewport Sizes

RBCv3 also enables you to specify larger view port sizes for our browsers when running your checks. This allows you to run checks that more closely mirror the experiences of your users, as well as better measure the performance metrics of downloading and rendering content for larger screens. Note: previously the default desktop size was 1280 x 917, which is a common view port size but smaller than many popular displays.

A Capable Foundation

With the release of RBCv3, Rigor is not only improving our the precision of checks as well as delivering new features, we are laying a capable foundation for the future. Leveraging the latest version of Firefox ESR, we gain access to cutting edge browser APIs and capabilities. This will enable us to add more features and measure additional properties of how browsers load and render webpages.
