Orion is a fast, highly customizable browser built on WebKit but individually compatible with both Chrome and Firefox extensions. There’s a built-in content blocker, and on the macOS version of Orion, you can import custom blocklists and add your own filtering rules. Cross-device sync via iCloud is excellent. Orion is still in Beta (January 2024). The devs are really open to feedback and suggestions, and there are frequent updates and improvements.
