Does the computer really send requests to their server when I open dev tools? I checked and I couldn't find any request that was sent from Firefox or Chrome when I opened dev tools.
Aren't they using a JavaScript based detection mechanism like listening for browser events on the client side or latching on to debugger to pull this information? Sounds to me like they are going out of their way to pull private information from my system that I or my system or my browser had no intention of sharing with them.
Check your console instead of the network tab - it will load css.map and js.map files. I never noticed until now, but .map requests don’t show in the network requests.
