Overscripted! Digging into JavaScript execution at scale
We set out to explore the unseen or non-obvious JavaScript execution events that are triggered when a user visits a webpage, and all the first- and third-party events that are set in motion when people retrieve content. To help enable more exploration and analysis, we are releasing our full set of data about JavaScript executions. This post introduces the dataset, how it was collected, and the decisions made along the way. We’ll share examples of insights discovered and provide information for participating in the associated Overscripted Web: A Mozilla Data Analysis Challenge, which we’ve launched today with Mozilla’s Open Innovation Team.

Developer survey results: libraries and cross-browser on mobile?
At Mozilla, we are dedicated to keep the web open and independent of a single company or technology. This means that users should have a choice of browsers and technology to use to go online and should not be blocked out because they can’t afford a certain device or are forbidden to change their browser.

There is no simple solution for local storage
TL;DR: we have to stop advocating localStorage as a great opportunity for storing data as it performs badly. Sadly enough the alternatives are not nearly as supported or simple to implement. When it comes to web development you will always encounter things that sound too good to be true. Sometimes they are good, and all […]
