User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:98.0) Gecko/20100101 Firefox/98.0

Steps to reproduce:

Have two windows open at the same time

Actual results:

Massive performance drop (youtube drops 60%+frames even on low quality videos with a ryzen 9 3900X and geforce 3800 FE, 32GB ram)

Expected results:

Multiple windows should not have a direct influence on the performance beside the expected amount.

Hi, is this performance drop limited to youtube?

In general it would be very helpful if you could try to record a profile when this happens (see https://profiler.firefox.com/), showing the difference between having one and two windows.

Thanks for your support!

It was not linked to youtube but it was most noticeable with video. Somehow it went away today.
