Orion is a fast, extremely customisable browser built on WebKit but uniquely aiming to be compatible with both Chrome and Firefox extensions. There is 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 (Jan 2024). The devs are really open to feedback and suggestions, and there are frequent updates and improvements.
