Firefox refresh rate is not on sync with the display refresh rate
Hello team,
I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.
I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.
Am I missing an existing option that could be changed or is it something available at the moment?
Thank you, Arsen

In Firefox you can configure the refresh rate by going to about:config and setting the layout.frame_rate preference.
The preference "layout.frame_rate" has 3 meanings depending on the value:
- -1 = Auto (default), use hardware vsync or software vsync @ 60 Hz if hw vsync fails.
- 0 = ASAP mode - used during talos testing.
- X = Software vsync at a rate of X times per second.
So you could set its value to 120 to switch your frame rate.

Thanks a lot, that did it!
