Why does the new Microsoft Edge consume less RAM than in Firefox when playing YouTube videos?

more options

Hello, I hope you are doing well reading this. I have been testing the new Microsoft Edge for these last 5 months, in November 2020 I decided to switch to Firefox because it is more secure, it blocks more trackers than Microsoft Edge, it is more interactive. But because in Microsoft Edge I can reproduce content in 720p with total fluency while consuming less RAM, which instead of Firefox than 720p videos I have freezes the video, but the sound continues to operate while consuming more RAM than Edge, My PC is a low-resource PC, I have 4 GB of RAM and I have a virtualization of 8 GB of RAM on the hard disk, the truth is that in 420p I do not care, but every time I enter YouTube it is tedious that it automatically assigns me the quality in 720p in the videos, the video freezes when starting, but the audio continues, I have to manually put it in 420p and when consuming more RAM than Edge the browser freezes because it reaches the limit of RAM and memory crashes, (while I'm trying to set it to 420) .. I know, they'll tell me "turn off autoplay and voila" there are times when web pages ignore autoplay and keep showing animated or video content, such as in canva, Duolingo and many more news pages that I have visited ... I have also seen that Vimeo assigns me the quality of 720p, then the same thing happens to me as on YouTube (video freezes, audio continues, Firefox not responding, memory crashes, trying to change the playback quality)

I don't know why Firefox playing 420p content manages to consume 652MB of RAM, with the only YouTube tab open. I have disabled hardware acceleration in Firefox options and set the content process limit to 1.

Why in the browser comparison of the official Firefox page when compared to the new Microsoft Edge does not mention the RAM?

Hola, Este es el foro en español, para reproducir videos el Firefox se apoya mucho el procesador de video, si estas usando un driver genérico por ejemplo de Microsoft el rendimiento en la reproducción sera malo. Por este motivo se recomienda drivers actualizados. Yo estoy utilizando la versión Nightly (como una versión alfa): adjunte 2 capturas de la pruebas que realice y eso que tengo una placa de video bastante vieja HD5450. Desactivar la aceleración por hardware si tienes una placa de video con su driver instalado no es recomendable. También mas complementos activados es mas consumo de memoria. Igualmente Firefox nunca se caracterizo por administrar la memoria al mínimo, anteriormente era normal llegar a 1GB de memoria con varias paginas y complementos activados, quizás las nuevas versiones administren mejor la memoria, como resulto la prueba que realice. Saludos

¡Hola Lucas!

Sería bueno que pegaras el resultado de medir la memoria en la página about:memory de tu Firefox en https://paste.mozilla.org/ para ver más claramente el consumo.

¡Gracias!

Hola Lucas, Escribí about:memory en la barra direcciones, luego presiona enter, en la ventana que aparece tienes el botón "Measure" para comenzar la medición y el botón "Measure and save" para salvar la medición realizada. Saludos
