A Mozilla engineer says Google’s redesign has made YouTube slower on Firefox and Edge.
Chris Peterson, the software community’s technical program manager, tweeted on Tuesday that the video sharing site loads at a fifth of the speed on non-Chrome browsers due to its architecture, as first reported by Sofpedia.
“YouTube’s Polymer redesign relies on the deprecated Shadow DOM v0 API only implemented in Chrome,” he wrote.
“YouTube serves a Shadow DOM polyfill to Firefox and Edge that is, unsurprisingly, slower than Chrome’s native implementation. On my laptop, initial page load takes 5 seconds with the polyfill vs 1 without. Subsequent page navigation perf is comparable.”
He notes that YouTube “still serves the pre-Polymer design” to Microsoft’s Internet Explorer 11, which launched in 2013 and has been replaced by Edge, and suggests that Google could have taken the same approach with Edge and Firefox.
Responding to Peterson’s claim, a Google spokesperson said the company found that overall YouTube performance on Firefox is the same as it has been since the site redesign, based on the latest metrics.
It says that it’s is always working to make YouTube faster, regardless of the browser you use, and will continue to do so. The company says it isn’t perfect and recently fixed a bug that helps improve Firefox performance — when it finds performance bugs impacting users for any browser, it fixes them.
