A:Answer Yes to working with Firefox, chrome, brave and windows edge/explorer - could be more but I've used all of those successfully. Additionally, I have windows 10, don't know about windows 11, but I dont see why it wouldn't work. There are no issues with it working with any program or computer. I have Dell, Microsoft and Cyber power computer brands and they are all connected to this logitech wireless keyboard and mouse. Absolutely love the switching between computers. Only downside is that if you have a slow computer, the keyboard and mouse may be slow to respond or 'stutter' in response because the connection is slower to receive and respond. I found this on my dell laptop that is older and slower.
