Same for another cross-EU migrant here.

Moving countries and languages means the translate function becomes a priceless necessity on a daily basis, and Chrome's and Edge's built-in translation features are second to none, so I switched away from FF when I moved country. Firefox third party translation addons exist but they always felt clunky and flaky being often slower and sometimes failing where Chrome and Edge would breeze through.

Better privacy is nice but convenience and saving time and frustration is nicer. Beret me all you want but it's not a hill I'm willing to die on.
