Mozilla has deployed an update for Firefox which fixes a persistent problem which affected Internet users visiting YouTube. It is version 127.0.2 of the software that must be installed.
It’s a seemingly innocuous update, but it resolves a stubborn problem that Internet users have reported in recent months: launching videos on YouTube did not work well with the Firefox web browser. The testimonials all pointed to a loading time that was too long before reading.
This malfunction was addressed on June 25 with the release of version 127.0.2 of Firefox.
“ Fixed an issue where YouTube playback stuck under certain conditions », Details the patch note. The incident was reported in February and more recently at the very beginning of June on Mozilla’s bug tracking tool. The update also fixes another glitch, of much less importance.
The failure was linked to a problem with buffering of YouTube videos. There was a problem multiplexing the bitstream with the VP9 codec that Google uses on YouTube. To put it simply, there was a one-off difficulty linked to combining several digital data streams.
The VP9 codec, designed to optimize bandwidth use, is no longer young. Widely used now, including Firefox, it is about to be replaced by AV1, which is its natural successor. It already appeared on YouTube in 2018 and Firefox has supported it since 2019.
