Hi, I've been using your browser for a very long time and I like everything in it so I don't want to switch to another one. Recently bought a laptop with the FN key which is very helpful when working with a laptop. A friend recently showed me that Chrome has a function to rewind, stop, increase, decrease the volume via the FN key and F2 or F3. I decided to try it with my browser and I didn't succeed. What can this be related to? Please help me.

Sincerely, Denis

I think Firefox supports some keyboard media keys because users have posted that they want them to also work when they have switched applications. (Firefox does not monitor media keys when it is not the active application.)

However, it's possible that Firefox doesn't understand your particular Fn key combinations. If you search your brand specifically, can you find any more information?

My laptop uses Fn+F2 for volume down and Fn+F3 for volume up, but that is the overall Windows output volume, not for a video player in a page in Firefox. I suspect Firefox doesn't even see those.
