Essential if you want to update USB devices over a website. (You need to install an additional app form this dev to work!)

I followed the instruction and it works under Linux!

The only catch was that to be able to actually open the port in Firefox, I had to give myself the permission to access it by doing "sudo chmod a+rw /dev/rfcomm0" in a terminal window (without the quotes).

"rfcomm0" is what the bluetooth manager called it - it's a serial port over bluetooth. With a plain old usb cable serial port, the port is called something like /dev/ttyACM0 . Do "ls /dev" before connecting the cable and then after and look for the new entry that's showed up.

Working on Ubuntu Mate Release 24.04.2 LTS and Firefox 138.0.4 (64 bit)

Finally I can debug my web apps needing device access in my favorite browser! Great work. It's a bummer that Mozilla org refuses to implement these features natively. Browsers are also a major app platform and has been for years, if not decades. Weird that it's still controversial for some.

Works like a charm. Thank you for adding this missing feature to Firefox!

Does exactly what I need so I no longer need to use chrome/edge/opera/etc for web based tools, very cool

This should be a standard feature idk why firefox is so unwilling to implement it

It was hard to find bundled .exe installer. But I'm finally happy with the working add-on
