We’ve collected a list of seven things to do about browser leaks, everything from utilizing a good VPN to changing to a more secure browser and installing the best browser extensions.
Online privacy is a much larger concern than it used to be. With surveillance efforts, spying ISPs, and cyber criminals lurking around every corner, it’s practically impossible to be too paranoid these days. That’s why when it comes to browser and VPN leaks, you need to be prepared.
There are a lot of things that go into the browser leaks category. Private data, personal information, identifying facts such as which browser you use or where you’re located. There isn’t one single fix for all of these problems. Instead, there are multiple things you need to do to lock down your browsing privacy and protect your IP address. We’ve got the full scoop in our guide to fixing browser leaks below.

First, get a reliable VPN
A reliable virtual private network (VPN) offers a ton of benefits, extending far beyond fixing certain leaks and keeping your data secure. You can hide your identity easily with a VPN, all thanks to strong data encryption. You can also switch virtual locations and bypass censorship firewalls with ease, all without lifting a finger.
Choosing the right VPN isn’t as easy as you might think, however. There’s a lot of data to sift through and compare. In general, look for a service that offers DNS leak protection and automatic kill switches, has fast servers, offers lightweight apps, and runs a strict zero-logging policy in as many areas as possible.
We did the research and found the top VPNs on the market that can help keep you safe. The results are listed below.

Next, fix these five types of browser leaks
Not sure what part of your browser is leaking, or if there are any leaks at all? Run a quick test on doileak.com or Panopticlick, then evaluate the results and use the fixes below to stay safe.
1. IP address leaks
IP address leaks only occur when you are connected to a VPN. The service is supposed to replace your IP address with a non-local IP. If a leak happens, though, websites will identify your real IP address instead of the virtual one, thus destroying your online privacy and anonymity.
The good news is that IP address leaks are only a browser problem if you connect to your VPN through a browser extension. Even in this case, you won’t need to change your browser settings to fix the leak. Instead, go to your VPN’s support pages and search for solutions to IP address leak problems. Chances are there’s a problem with the add-on itself. Worst-case scenario is you install a VPN app instead of using the extension.
To determine whether or not you have an IP address leak, use an online tool such as ipleak.net. Visit the site in your browser and wait for the scan to automatically run. If a leak is detected, you’ll be notified.
2. Memory leaks
Memory leaks occur when a browser or browser add-on starts hogging your system’s memory thanks to poor programming practices. Essentially, memory allocated from your device to run the browser is used by the program. When it’s done with the section of memory, it’s supposed to return it to the operating system. This doesn’t always happen, though, resulting in a much larger memory usage footprint.
Fixing a memory leak requires locating the source of the leak itself. There are several main areas where a leak can occur, including web pages themselves, the browser engine, and certain add-ons. The only way to fix the first is to not use the web page causing the leak. The second requires switching browsers. The third simply involves uninstalling the add-on.
Browser memory leaks are frustrating, but unfortunately there’s little you can do about them. It’s up to the programmers to detect and patch these issues before they arise.
4. Browser privacy leaks
This is a big category of browser leaks, but arguably the most important. Browsers transmit a ton of information from our devices. They hold passwords, e-mail content, visited websites, movie streams, and so on. Websites interfacing with your browser must learn a little bit about you before they can share data. In the case of browser leaks or malicious website scripts, your system shares a little too much information.
Plugging up privacy leaks is a simple matter of protecting yourself with the right software and add-ons along with smart browsing practices. To get started, we recommend using Firefox or Brave, two browsers that put your online privacy at a premium. Next, look into the extensions listed below, all of which lock down your data to prevent information leaks.
- uBlock Origin – There are tons of adblockers around, but the only one that maintains top-level trust is uBlock Origin, as it’s fully open source and protects from more than just malicious ads. Make sure you install uBlock Origin, not uBlock.
- HTTPS Everywhere – HTTPS Everywhere is a browser extension made by the Electronic Frontier Foundation (EFF). It forces websites to use a secure HTTPS connection for every element on the page, ensuring no data entering your device isn’t encrypted beforehand.
- NoScript – A script- and tracker-blocker designed to prevent browser fingerprinting and click hijacking tactics.
- Privacy Badger – Another extension made by the EFF designed to protect your online privacy. Simply put, Privacy Badger automatically learns to block invisible trackers that attempt to steal your data.
5. WebRTC leaks
WebRTC stands for Web Real-Time Communication, a free and open source project launched in 2011 that provides web browsers with a simple interface for exchanging audio and video communications without installing additional plugins. WebRTC leaks are often associated with VPNs, but the reality is they are straight-up browser vulnerabilities.
WebRTC leaks present a potential weak spot for cyber criminals to exploit. Any website receiving requests from your browser, even encrypted and anonymous requests, could theoretically run certain commands to determine your real IP.
You can test for WebRTC leaks by visiting ipleak.net, waiting for it to run a standard IP address test, then looking at the section that says Your IP addresses – WebRTC detection. If a leak is shown, you should look into repairing it right away.
It’s easy to fix this type of browser leak. All you have to do is visit your configuration page or install a certain add-on and you’re safe. Learn more about WebRTC leaks before you do that, or jump straight to our featured article about fixing WebRTC leaks for Chrome, Firefox, Opera, and Yandex.
Finally, change to a more secure browser
One of the best things you can do for your core security is to use a browser that puts your privacy first. Microsoft Edge, Safari, and Chrome might be popular, but they aren’t necessarily the top choices when it comes to staying safe online.
Firefox has long been the browser of choice for anyone interested in protecting their online privacy. Part of this has to do with the browser’s open-source nature, which allows anyone to take a peek at the code to make sure everything is as air tight as it’s supposed to be. Another factor is the browser’s many privacy-oriented extensions built to prevent data leaks and attacks of all types.
Beyond the browser itself, Firefox is maintained by Mozilla, a team that actively fights for digital privacy causes. Chrome is made by Google, a company that is known to collect and use personal data. With Firefox, there’s no impetus to violate your rights, giving the browser a strong privacy slant from the ground up.
Firefox is the best all-purpose browsing solution for anyone interested in a fast, safe, and secure web experience. Download Firefox for your favorite device and get started today.
Brave is an open-source browser project launched by the original co-founder of Mozilla. Its purpose is to deliver a secure web experience without sacrificing usability. It’s loosely based on the Chromium engine, which powers Google’s Chrome browser, but it comes with a number of added privacy features that make everyday web use more secure, no extensions required.
Apart from its built-in ad blocking feature, Brave also delivers phishing and malware protection, script blocking, browser fingerprinting protection, and HTTPS Everywhere, all built into the browser itself, no add-ons required. Everything can be configured to your liking through the orange shield button, but for the most part, you can download Brave and start enjoying a better internet experience right away.
When it comes to raw security and privacy, nothing can beat the Tor Browser. The software is built upon a Mozilla core that leverages onion routing to encrypt and redirect every packet of data that leaves your device. Data is passed through a series of nodes that send packets back and forth to obfuscate the origin, making it practically impossible for anyone to tell where a packet came from. This means everything you do in the Tor Browser is about as anonymous as you can get. Leaks are practically impossible since every part of the browser is built to keep you safe.
The Tor Browser comes with a host of default security features that eliminate possible breaches of identity. Technologies like Flash, Java, or embedded applets are disabled by default, since they can potentially cause information leaks. This means you won’t be able to do things like watch videos or play games in your browser, but it also means that leaks are a thing of the past.

Browser leaks are frustrating, but there are plenty of tools you can use to stay safe online. Whether it’s choosing a better, safer browser, installing the right add-ons, or simply digging in and patching the leak yourself, the power of online privacy is in your hands.
