Tired of Browser Extensions That Don't Actually Help?

If you’ve tried blocking distractions before, you know the frustrations:

Extensions with barely any features beyond a basic blocklist

Clunky interfaces that feel like they were built in 2010

Tools that only work on Chrome and ignore your other browsers

Extensions that require a separate desktop app just to function

“Blockers” you can disable in two seconds when temptation strikes

Simple Blockers Leave You Wanting More

Most browser extensions offer a basic blocklist and nothing else.

No focus sessions. No smart locks. No daily limits.

And when you really need them, they’re too easy to turn off.

DigitalZen is different. It’s a full-featured productivity tool that lives right in your browser — lightweight enough to forget it’s there, powerful enough to keep you on track.

DESKTOP APP

Need More Control? Upgrade to the Desktop App

The DigitalZen extension is a powerful productivity tool on its own. But if you find yourself disabling the extension in moments of weakness, or need to block desktop apps and games — the desktop app takes your focus to the next level. 

 

The extension is for users who want a productivity boost with basic self-control.

The desktop app is for users who need real control over procrastination.

Upgrading is seamless — just click “Download App” inside the extension. Your settings carry over automatically. No re-setup needed.

FAQ

Browser Extension Website Blocker FAQ

Q: Which browsers does the DigitalZen extension support?

Over 30 browsers! All Chromium-based browsers (Chrome, Edge, Brave, Opera, Vivaldi, Arc, Yandex, Zen Browser & more), Firefox-based browsers (Firefox, LibreWolf, Waterfox, Floorp, Tor Browser & more), and Safari. Same features everywhere.

 

Q: What can I do with just the extension — no desktop app?

Almost everything! Website blocking, focus sessions, scheduled blocking, daily time limits, Pomodoro timer, all 6 smart lock types, and customizable templates. The only features exclusive to the desktop app are app blocking, uninstall protection, pre-built category blocklists, and cross-browser management from one place.

 

Q: Can I prevent myself from disabling the extension?

The extension itself can’t prevent you from removing it (that’s a browser limitation). If you need that level of protection, the desktop app offers uninstall and disable protection. Many users start with the extension and upgrade when they need stronger control.

 

Q: Does the extension work in incognito / private browsing mode?

Yes — you can enable incognito access in your browser’s extension settings for stronger protection. The extension works without it, but enabling incognito access closes that loophole. 

 

Q: Does the extension slow down my browser?

Not at all. At only 2.61 MB, DigitalZen uses fewer resources than a single browser tab. It runs quietly in the background.

 

Q: Does the extension need an internet connection?

Only for initial registration and certain network-based features (like emailing a friend your lock password). Day-to-day blocking works completely offline. 

 

Q: What permissions does the extension need?

The extension needs to see your active tab URL and access all sites to block effectively. For the strongest protection, you can also grant incognito access — but it works without full permissions too.

 

Q: How do I upgrade to the desktop app?

Just click the “Download App” button in the top-right corner of the extension. Your settings sync automatically — no need to reconfigure anything. The upgrade is completely seamless full permissions too.

 

Q: Is there a free version?

Yes! Installing the extension gives you a 14-day free Premium trial. After that, you can continue using the extension for free on our Basic plan, or upgrade to Premium (with or without the desktop app) to unlock all features.

Q: Can I sync settings across multiple browsers?

Full cross-browser sync is a desktop app feature. With the extension alone, each browser has its own settings. When you install the desktop app, everything syncs from one place.
