This is a feedback/idea item.
As of, I think, FF 156.0, the visibility of certain radio button selections has decreased significantly. I encountered this using Facebook, setting a Reel's 'playback speed'. All the choices formerly had visible circles to their left, with the currently selected one having a dot in its circle. Now, the circles are VERY dim, which I find harder to instantly interpret. [See attached screenshot.]
I realize that this COULD be caused by Facebook changing some STYLE choices... Whether it's FF or FB, I'd like it changed back.
I thought that perhaps the Settings > Website appearance > System/Light/Dark might be affecting this, but I tried all three choices and the results were the same.
If you view the reel in a 'full-page' view, which you get if you open the address (URL) of the reel rather than viewing it in your FB Feed, the radio buttons look very much like they used to.
