You should inform yourself before writing. And I say that without any harmful intent. To get a true privacy focused Browser you need to harden Firefox (and may download some scripts from github to do so). Or just use LibreWolf as it has a lot of tracking preventative stuff built in similarly to Mullvad Browser or Tor Browser. Those two are however of course still way better. The latter being the best with regards of anonymity if you know what you are doing.
I can just encourage you to inform yourself about the Firefox browser which is better than Chrome of course, but still compromises your privacy in the default shipped state.
Technical data includes information about your Firefox version and language, device operating system and hardware configuration, memory, basic information about crashes and errors, outcome of automated processes like updates and safebrowsing. When Firefox sends data to us, your IP address is temporarily collected as part of our server logs. IP addresses are deleted every 14 days.

I have informed myself. There is nothing personally-identifiable in the data Mozilla collects in Firefox: https://support.mozilla.org/en-US/kb/telemetry-clientid
You seem to ignore information collected about you is collected information about you.
This seems like and IS personally identifiable information….
