Mind Wall от XX88

Mind Wall helps you protect your attention when it matters. Turn on focus mode and any site on your blocklist will be redirected to a simple reminder page instead of loading. You can manage the list from the popup: add a host by typing it in or add the page you’re on with one click. A built-in timer lets you run focused sessions from a few minutes to a couple of hours and automatically turns focus off when time is up. Everything runs locally in your browser — no accounts, no tracking, and no data sent anywhere so you can get a quiet workspace with zero friction.
