Even if you do 'install' and 'first run' tracking without the unique identifier you need to have consent for EU citizens before sending the tracking request to Mozilla. As the IP is transmitted you would already be sending what the regulations call 'personal data'.
The ID is just additional data that would probably be classified as PD (personal data) as well.
So even basic install tracking is a no go. I also just don't understand why this would be necessary. This wasn't the case for software for how many decades? It didn't necessarily transmit such information. If it was commercial you probably had something like license server stuff in the later days (before just a number that was checked for validation).
It probably became a thing when the mobile phone with app model rose. There the vendors (mostly Apple/Google) knew the downloads from the app stores and marketing wanted more. Especially when the pushed advertisements for apps.
So companies like Adjust rose to fame for tracking ad clicks to installs, first run and usage stats.
This probably led to others thinking it to be a great idea for general software as well.
