How to Install and Use a Link Safety Extension on Chrome, Firefox, and Edge
Back to all blogsInstalling a link safety extension takes less than two minutes and protects you from malicious links every time you browse. This step-by-step guide shows you how to install CyberCheck360's free Link Inspector extension on Chrome, Firefox, and Edge and start protecting yourself from phishing links today.
Stop Clicking Links and Hoping for the Best
Most people have no way of knowing whether a link is safe before they click it. It looks fine. The sender looks legitimate. The URL looks close enough to the real thing.
And that is exactly what makes phishing links so effective.
A link safety browser extension solves this problem without requiring any technical knowledge. It installs in minutes, runs quietly in the background, and checks every link before you reach the destination. If something is wrong, it tells you. If everything is fine, you never notice it is there.
This guide walks you through how to install CyberCheck360's free Link Inspector extension on Chrome, Firefox, and Edge, and how to use it once it is set up.

Here is what it does automatically in the background:
- Checks every link against CyberCheck360's live threat intelligence database
- Warns you when a domain was recently registered, which is one of the strongest signals of a phishing attack
- Uses AI to detect login pages that are impersonating legitimate brands like Microsoft, Google, or your bank
- Follows redirect chains to check where a link actually leads, not just where it appears to go It is completely free. No account required. No subscription. No configuration needed to get started.

How to Use Link Inspector After Installation
Once installed, Link Inspector works automatically. You do not need to do anything differently when you browse. Here is what to expect.
When You Hover Over a Link
Link Inspector checks the URL in the background as you hover. If the domain is flagged as malicious or newly registered, a warning badge appears before you click. This gives you a chance to decide whether to proceed before committing to the visit.
When You Click a Link
A full real-time check runs the moment you click. The extension follows any redirect chain to check where the link truly leads, not just where it appears to point. If the final destination is suspicious, access is blocked and you see a clear warning explaining what was found.
When You Visit a Page With a Login Form
This is where Link Inspector goes further than most free extensions. When a page contains a login form, the extension's AI analyses whether the branding on the page matches the actual domain. If the page looks like a Microsoft or Google login but is hosted on an unrelated domain, you get an immediate warning before you type a single character.
When a Link Is Clean
You are taken straight to the destination with no interruption. Link Inspector only alerts you when something is actually wrong. Clean links pass through silently.
Tips for Getting the Most Out of Link Inspector
Pin the extension to your toolbar. Keeping the Link Inspector icon visible in your toolbar lets you check its status at a glance and access settings quickly if you need to adjust anything.
Pay attention to domain age warnings. If Link Inspector flags a domain as newly registered, treat it with caution even if the page looks legitimate. Attackers register fresh domains specifically to avoid detection. A warning does not always mean a link is malicious, but it is worth pausing before entering any personal information.
Use it alongside your email security tools. Link Inspector protects you across your entire browser, not just in email. It is most powerful when used in addition to whatever email security your workplace or email provider already has in place, not instead of it.
Share it with your team or family. Link Inspector is free for everyone. If you work in a small team or want to protect less tech-savvy family members from phishing links, sharing the install link takes seconds and can save a lot of trouble.
Frequently Asked Questions
Is Link Inspector free to use?
Yes. Link Inspector is completely free with no subscription and no account required. All core features including real-time threat intelligence, domain age warnings, and AI-powered login page analysis are available at no cost.
Does Link Inspector work on Microsoft Edge?
Yes. Edge supports Chrome extensions. You can install Link Inspector from the Chrome Web Store and it works identically on Edge as it does on Chrome.
Will Link Inspector slow down my browser?
No. The extension is designed to run lightweight background checks without affecting your browsing speed. Most checks complete in milliseconds and are not noticeable during normal browsing.
What does it mean when Link Inspector shows a domain age warning?
It means the domain you are visiting was registered recently. Newly registered domains are a common signal of phishing attacks because attackers create fresh domains to avoid reputation-based detection. The warning does not always mean the site is malicious, but it is a signal to be cautious, especially if the page asks for personal information or login credentials.
Can I use Link Inspector on my work computer?
Yes, as long as you have permission to install browser extensions on your work device. Link Inspector works alongside existing corporate security tools and does not interfere with other extensions or security software.
Does Link Inspector track my browsing history?
No. Link Inspector only processes URLs at the point of checking them against the threat intelligence database. Your general browsing activity is not tracked or stored.
What should I do if Link Inspector blocks a link I think is safe?
If you believe a link has been incorrectly flagged, you can report it through the extension. False positives do occur occasionally with any threat intelligence system, and user feedback helps improve the accuracy of the database over time.

Installing a link safety extension is one of the simplest and most effective things you can do to protect yourself online. It takes less than two minutes, costs nothing, and works quietly in the background from that point on.
