I wonder how much this affects things if you’ve already gone through Firefox’s settings to max out privacy and turn off all telemetry.

I resisted switching to Librewolf because Firefox works great (including M365 in Linux at work) and seemed to have the options you’d want for privacy and security.

This doesn’t feel like an emergency, especially in a chrome/edge dominated world. But it’s back on the list of things to investigate transitioning away from.
