Does blocking a site in Edge block it everywhere?

No. An Edge extension or setting only affects Edge — the site still opens in Chrome, Firefox or incognito. To block a site across every browser and app, use a system-wide tool like Kaizen Focus.

How do I block a website permanently and stop bypassing it?

In-browser blocks are easy to switch off. A system-level focus app such as Kaizen Focus blocks sites across all browsers, can block apps too, and adds friction so the block actually holds.

How to Block Websites in Microsoft Edge

Q: How do I block a website in Microsoft Edge?

Use Microsoft Family Safety for a managed child account, or install a site-blocker extension from the Edge Add-ons store and add the sites you want blocked. Both work, but only within Edge.

Whether it's to stay focused or to keep a site away from kids, blocking a website in Microsoft Edge is a common need. Edge has a couple of ways to do it — but each has limits worth knowing before you rely on it. Here's how, and how to block a site properly across your whole PC.

Method 1: Microsoft Family Safety

If you manage a child account, Family Safety lets you block specific sites (or allow only approved ones) in Edge and enforce it on their device. Set it up at family.microsoft.com. The catch: it's designed for managed child accounts, not for blocking distractions on your own account.

Method 2: An Edge extension

You can install a site-blocker extension from the Edge Add-ons store, add the sites you want blocked, and it'll stop them loading in Edge. This works for your own account, but it has two weaknesses: it only blocks Edge (open Chrome or Firefox and the site loads fine), and an extension can be turned off in a couple of clicks when willpower dips.

Why browser-only blocking isn't enough

The problem with any in-browser block is that it's tied to one browser and easy to bypass — a different browser, incognito mode, or just disabling the extension. If you're blocking sites to actually change a habit, you want something that applies across every browser and app and isn't trivial to switch off.

Block sites system-wide with Kaizen Focus

Kaizen Focus blocks websites at the system level on Windows, so a blocked site is blocked in Edge, Chrome, Firefox and everything else at once. You can also block distracting apps, schedule focus periods, and set time limits — with the friction that makes a block actually stick. It runs locally on your PC.

Bottom line

For a quick block in Edge, an extension or Family Safety works. But because in-browser blocks only cover Edge and are easy to bypass, a system-wide focus app is the reliable way to block a website — and keep it blocked.
