I think Yucandu has (custom) hardware (like something based on an esp32 circuit board) that he wants to flash with new firmware, and you generally do that via a com-port (remnant of an old type of connector). Oversimplified: These days com-ports are simulated over usb, and (for now) only chrome-based browsers can actually send the firware over these simulated ports. An example is the flasher for Meshcore devices.
None of the browser based COM port uploader tools work on Firefox yet. Like the WLED installer or the ESP32 flash tools.
Firefox has it on beta versions or somesuch
I have no idea what any of that means

I… Don’t even see why you would want a browser to be able to do that. Seems like really trying to increase browser security issues on purpose.
Because it’s easy and convenient. I have esptool installed and I still usually flash via the browser.
