Ive used Firefox and chrome for a long time side by side and on a daily use basis there is not any discernable difference that’s caused by the browser. On Firefox, add the extensions ublock origin, privacy badger, and decrentraleyes to start with, and I’d recommend changing default search to duckduckgo or start page as well. Your entire web experience will be massively improved (Yes ddg and start page look and feel different. Search results are the same but without all the ads and misdirects)
