Facebook worked with Google and Firefox to help tackle the slow refresh problem, in what the described as “a great example of Facebook and browsers working together to quickly squash a bug.”
The changes have helped to dramatically improved page load times on the social media site.
In a blog post, Google's Takashi Toyoshima explained how Chrome made the changes. “Users typically reload either because a page is broken or the content seems stale,” he wrote. “The existing reload behavior usually solves broken pages, but stale content is inefficiently addressed by a regular reload, especially on mobile.”
Toyoshima added: “To improve the stale content use case, Chrome now has a simplified reload behavior to only validate the main resource and continue with a regular page load. This new behavior maximizes the reuse of cached resources and results in lower latency, power consumption, and data usage.”
