Features & Capabilities

🛡 Focus Guard – block distracting websites and protect your focus

Add the sites that pull you away from your work – social media, news, video – and Focus Guard replaces them with a calm reminder page whenever you try to open them.

✅ Block distractions – Blocks a site and all its subdomains. Type it any way you like (a full web address, capital letters, *.example.com); Focus Guard cleans it up. ✅ Instant – Blocking a site also blocks tabs that are already open on it. ✅ Profiles – Separate blocklists for Work, Study or Evening, and switch in one click. Each device keeps its own active profile. ✅ Your reminder – Show your own image on the blocked page, or keep the default. ✅ Backup – Export your profiles to a file and import them in another browser. ✅ Comfortable – Dark mode that follows your system, and a manager you can use with the keyboard.

🔒 Private by design • No accounts, no servers, no tracking, no ads. • Focus Guard makes no network requests at all. This is enforced by its security policy and checked by automated tests. • Your blocklists stay in your browser. If you use browser sync, your browser keeps them in sync across your devices through your own Google or Mozilla account. The developer never sees them. • Privacy policy: https://github.com/engtomhat/focus-guard/blob/main/PRIVACY.md

About the permissions • "Storage" saves your blocklists and settings. • "Access browser activity during navigation" (Chrome calls it "Read your browsing history") lets Focus Guard see which site a tab is opening, so it can check it against your blocklist. Nothing is recorded or sent anywhere.

✨ New in 3.0 • Open tabs are blocked as soon as you add their site • More room for domains in each profile • Export and import your profiles • Dark mode and keyboard-friendly manager • Clear messages when a domain can't be added

Free and open source (GPL-3.0): https://github.com/engtomhat/focus-guard Works in Chrome and other Chromium browsers, and in Firefo

Is Focus Guard Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Focus Guard requires very minimum permissions.

Risk impact analysis details

High Allows retrieval of a user’s browsing history, presenting a notable privacy risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Focus Guard is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
