SDR Web Radio od RiveraSoftWare

This extension is firstly intent to activate the audio in the chrome browser for WebSDR server pages, now firefox compatible too, but you can also make use of Mute, Squelch, Autonotch, as well as buttons to control frequency and volume and modulantion mode selectors althought not limited, in the future another features like ft8 could be added.

Some features like Sticky might not work in modified standard pages. The mouse wheel function does not work on touch screens at least you install a plugin program on Windows like TouchMe Gesture Studio. On laptops you could need to activate the touch pad virtual scrolling.
