At work I guess you only do work related stuff, so at the end of the day it’s only work-related data that the browser has access to. Why would it matter to you?

99.9% of my the personal browsing I do is in firefox both on phone and desktop, but on work laptop I use Edge because 1. the work web-apps seem to favour chromium based browsers and 2. it’s not my data so I don’t really care about the privacy of my company’s data, they have a data privacy officer to worry about that.
