Feeling like a little slow on Firefox and Edge browsers? You are not the only one to think so.
On Tuesday, a Firefox developer claimed that YouTube was running five times slower on both browsers than on Chrome. "On my 1 Gbps Internet, it takes 5 seconds in Firefox and Edge and 1 second in Chrome," Mozilla program manager Chris Peterson said on Twitter.
He went on to say that Google – which owns YouTube – has effectively adapted the streaming service to work better on the company's browser compared to competing products.
In his own tests, Peterson found that even though a YouTube video would load quickly on Firefox and Edge, other content such as the comments section and the right bar suggesting Other videos would appear in gray boxes, before finally charging after five seconds.
I am measuring the time that YouTube takes to replace the gray placeholder areas of its wired layout with real text when reloading a page. On my 1 Gbps Internet, it takes 5 seconds in Firefox and Edge and 1 second in Chrome.

What causes slowdowns? Peterson blames YouTube's decision a year ago to use Polymer, a Javascript library for developing web applications. At the time, YouTube indicated that this decision would pave the way for faster development of features.
But according to Peterson, the redesign of Polymer on YouTube is also based on an "obsolete DOM v0 API" that has only been implemented in Chrome. Firefox and Edge, on the other hand, have eliminated the old API. As a result, when browsers visit YouTube, they will essentially need to load more code, which can lead to slowdowns.
"YouTube launched a new design knowing that it was much slower in other browsers." . "The new design could have been built using a different framework that looked and achieved the same for all users instead of" Better Display in Chrome. ""
Up to now, Google, Microsoft, and Mozilla have not officially commented on tweets, but this is not the first time people have complained about Polymer's design on YouTube. " , which causes slowdowns on Firefox A year ago, some users of Reddit also noticed the problem.
At PCMag, we did not notice any significant differences in loading times during Access to YouTube via Chrome or Firefox If you have, Peterson tweeted fixes for Firefox and Edge which involve the installation of browser extensions who will load the old YouTube interface, which is free of Polymer's implementation.
