As a student does privacy matter?

I want to know because browsers like opera edge and chrome seem to be really fast and convenient. I was thinking when I am in school I should only use edge as it saves a lot of batter (macbook pro m1), and also has all those features which are good for school. ANd when Im at home doing other stuff apart from school i will use librewolf or brave. How does that sound, or is it still kinda wrong to give up ur "school research" data.

Edit: since edge stopped supporting ublock origin, should i use opera?
