Is there any way to change the actively used GPU for hardware acceleration?

I am using 2 monitors for my setup, one is connected to my dedicated GPU and one is connected to the internal GPU on my processor. My main Monitor is connected to my dedicated GPU for performance reasons and I would like to keep it that way. The problem is that, as soon as I open Firefox on my second monitor, the processing of video files, etc. is still done on my dedicated GPU. This leads to way higher usage of both GPU's compared to processing the data on the Device feeding the respective monitor. Is there any way to choose the GPU Firefox is using so it becomes less of a ressource hog? I know it has to be somehow possible because: a) When choosing my iGPU as primary Monitor, Firefox also switches hardware acc. to that GPU b) Microsoft Edge does it automatically (that is a silly reason, I know. But still.) I appreciate any help you guys might have.

Doesn't your GPU have dual outputs? How are your iGPU and GPU set to function as one video display?

Yes, my GPU has dual outputs, but I want the iGPU to handle the workload of the second monitor. When playing a game on my main monitor for example, I don't want the video decoding workload (maybe a youtube video on my secon monitor) on my main card. Most of applications seem to adjust the used GPU based on the display, but for some reason FF doesn't do that. The funny thing is that, as I said earlier, when I switch the primary Display in the OS's settings, firefox chooses to do all hardware acc. on my iGPU.

Here's more read on your iGPU and GPU.

It doesn't sounds like what problem here is related to FF itself.
