Do you feel YouTube is running a bit slowly on Firefox and Edge browsers? You are not the one who believes it.
On Tuesday, a Firefox developer claimed that YouTube runs five times slower on both browsers compared to Chrome. "On my 1Gbps internet it takes 5 seconds in Firefox and Edge and 1 second in Chrome." Mozilla Program Manager Chris Peterson said on Twitter.
He continued to claim that Google – which owns YouTube – tailored the streaming service effectively to run better in the company's browser over competing products.
In his own test, Peterson found that while a YouTube video itself loads quickly on Firefox and Edge, other page content like the comment section and the line on the right would recommend that other videos first appear as gray boxes before you finally loading after five seconds.
I measure the time YouTube takes to replace the gray boxes with wireframelayout with real text when uploading a page. On my 1Gbps internet it takes 5 seconds in Firefox and Edge and 1 second in Chrome.

However, according to Peterson, YouTube Polymer redesign is also dependent on an "outdated Shadow DOM v0 API" that is only implemented in Chrome. Firefox and edge, on the other hand, phased out the older API. As a result, when browsers visit YouTube, they must essentially load more code, which can lead to slowdowns.
"YouTube launched a new design that knew it was significantly slower in other browsers," Peterson tweeted ". "The new design could have been built using another framework that looked and performed the same to all users instead of" Best viewed in Chrome. " ""
So far, Google, Microsoft and Mozilla have not officially commented on Peterson tweets. But it's not the first time people have complained about YouTube Polymer design that causes slowdowns over Firefox. A year ago, some Reddit users also identified the problem.
Here at PCMag, you have not noticed a significant difference in load times when you open YouTube via Chrome versus Firefox. If you have, Peterson has tweeted corrections for both Firefox and Edge which involves installing browser extensions that will load YouTube's older interface that is free from polymer implementation.
