Is there a way to generate something like a "computer id" that will be different on each computer on from a firefor and chrome extension to use for tracking purposes?
I mean, I want each extension installation to have a unique id that will be always the same on that computer, but different on each computer.
The id doesn't need to be the same on both chrome and firefox extension
I end up just generating a random guid with js and storing it as a normal preference the first time the extension runs.
