Default Brave blocks ads more aggressively than default Firefox. Of course you can achieve that with Firefox + uBlock Origin, but add-ons are not available on iOS and iPad OS.
That's just my experience. I still use Firefox + Firefox Focus BTW. To block more aggressively, I also use VPN + Adguard Home.
This is actually not a good advice, from my experience. If we don't monitor, refactor, or improve the code, the software will rot, sooner or later. "Don't touch" doesn't mean we don't ever think about the code, but we make the conscious choice not to modify it.
