I use Firefox at home, but my work (large company) has standardized on everyone using Chrome to the point of writing custom Chrome extensions. So at work I use Chrome because it is essentially required. I wonder how many enterprise workers are in the same boat, even just due to security folks wanting to focus on a single browser and thus getting the company to mandate the use of Chrome.
Company can mandate whatever software they want. It’s their computer, their data, and their workflow. You’re not IT, so if they’re ok with sending data to Google, your hands are tied. I avoid doing any personal stuff on my work laptop. Even quick searches.
