iKKEGOL USB Single Foot Switch Control One Key Customized Computer Keyboard Action Pedal HID Yellow

I would like to use this to turn the mic on and off when i am using my dragon naturally speaking on my win 10 computer. will it w/o a big hassle? thax

How do I prevent it from opening a browser tab when holding the switch down? It opens a browser window automatically. Makes it useless.

Can more than one be supported on a PC? I want to use two of them on the same PC.

The install of version v6.9.3 is not working. i have .net 3.5 enabled, but it will not detect the foot switch. any reasons why?
