That’s just browsers with default settings. Firefox doesn’t have a built in ad block, so it will always perform worse in that test. I guess FF + ublock origin + hardened settings (such as arkenfox) would perform like brave, if not better.
For example, if you check android browsers, you see that Mull (a hardened fork of Firefox) performs great, even without ublock (that you can install as extension anyway).
