Years ago our company consolidated on Firefox because we could rely on it to not send our information to remote servers. At that time other browsers made it hard to disable telemetry. Firefox was then the only browser that could forward Kerberos tickets to remote servers, for highly secure two-factor authentication and single-sign on.

I'm personnally sad that now we have to consider banning Firefox for company use, because it's hard to verify that we've disabled every AI "feature" that might funnel our data to remote servers.
