You Don’t Need Many! 5 Security Extensions That Actually Matter

It only takes five lightweight extensions to turn a browser from a data-collecting vulnerability into your secure online gateway.

Together, they provide a layered approach necessary to identify and thwart as many attack vectors as possible.

Here’s what these extensions are, what they do, and why you’ll thank us for recommending them!

1. An Ad Blocker

The extension you should install first is also the one that will have the most dramatic positive impact on your overall browsing experience.

From a security standpoint, ad blockers are essential since they prevent direct contact with malvertising.

If there are no harmful ads to display, your chances of downloading associated malware or ending up on harmful websites decrease dramatically.

2. A VPN

You might already be using a VPN as an effective tool at the network layer, which comes in handy if you don’t want to risk monitoring and exposure when connecting through potentially dangerous networks like public Wi-Fi.

However, the VPN’s browser extensions might be an even better fit in some cases.

VPN extensions limit their scope to the browser. This means you can use them for IP masking and to block known malicious sites without impacting other programs, apps, or downloads.

They’re less resource-intensive while easily letting you turn VPN functionality on and off or create exceptions for specific websites.

3. A Tracker Blocker

Websites use tracking pixels, third-party cookies, browser fingerprinting techniques, and other tricks to develop a profile of you over time.

These are used to follow you across websites and serve personalized ads, hoping you’ll engage with them.

Tracker blockers observe website behavior and intervene if necessary. For example, they can flag external resources like fingerprinting scripts as you enter a website and keep them from loading.

Less data on you is accumulated and transferred that way. Plus, malicious scripts are less likely to trigger.

4. A Password Manager

Storing login details in your browser is convenient, but leaves them exposed. The best password manager extension is a safer alternative in several ways.

On the one hand, managers promote better password hygiene by seamlessly generating as many strong, unique passwords as you need.

There’s only one master password to remember, and you can use that to sync password access across devices.

Meanwhile, the passwords themselves are stored in an encrypted online vault whose contents the provider has no knowledge of.

On the other, password managers fill credentials automatically only for the websites associated with them.

This is helpful for preventing phishing attacks since you can use the lack of autofill on a fake website they might send you to as a sign of foul play, and go back before getting your account stolen.

5. A URL Cleaner

Links can contribute to tracking as much as a website. Depending on its structure, a link can hold a passive identifier that tells a website owner whether you arrived there through a Google search or by interacting with a newsletter.

It's another tactic that helps with profile building that tracker blockers typically don’t address.

Luckily, URL cleaners exist. They’re simple extensions that remove UTM parameters, causing you to enter websites via their original links.
