Do you find that YouTube videos seem more sluggish in Mozilla Firefox and Microsoft Edge than in Google’s Chrome? If so, you’re not alone.
Chris Peterson, an engineering program manager with Mozilla, recently claimed via Twitter that videos at Google’s YouTube load slower in non-Google browsers, specifically Firefox and Edge. To back up his assertion, Peterson cited his own tests over a 1Gbps internet connection, in which he measured the time YouTube took to replace its gray placeholder boxes with real text when reloading a page. Firefox and Edge took five seconds to complete this task, while Chrome achieved it in just one second.
Peterson blamed the problem on the recent YouTube Polymer redesign, which uses a deprecated API that’s implemented only in Chrome. Since Firefox and Edge no longer use this API, those browsers need to load more code for YouTube videos, leading to a slower performance.
Peterson also pointed the finger at Google, tweeting that “Ignoring the particular technologies involved, YouTube launched a new design knowing it was significantly slower in other browsers. The new design could have been built using a different framework that looked and performed the same for all users instead of ‘Best viewed in Chrome.'”
Google countered Peterson’s allegations, saying that based on its own metrics, overall YouTube performance on Firefox is the same as it has been since the Polymer redesign. But if you find YouTube performance not up to snuff on Firefox or Edge, fret not, for there is a solution, according to Peterson.
