    Are Chrome extensions safe?

    Not all Chrome extensions are safe, even if they claim to enhance your browsing security. Before downloading any Chrome extensions, look at user reviews — if you’re more tech-savvy, check out the extension’s code and permissions to gauge how reliable the developers are. 

    If you find bad reviews or bad code, you may want to remove the extension from Chrome if you’ve already installed it. You can also use a malware remover or adware removal tool if you think your device has been infected with a virus or some kind of adware.

    Choose a private browser for the ultimate protection

    No matter how secure they are, even the best Chrome security extensions aren’t going to keep your browser fully secure — especially because they’re plugged into the data-hungry Chrome browser. Using a private browser is your best bet for truly private browsing. 

    AVG Secure Browser is built with privacy and security at the forefront. In addition to always-on private browsing mode, AVG Secure Browser automatically blocks ads, forces HTTPS encryption, and blocks trackers so your activity can’t be mined for advertisers.

    And since it runs on the same Chromium platform as Chrome itself, all your favorite Chrome extensions will work with AVG Secure Browser as well.

    Now let’s explore the best browser security extensions for Chrome, sorted into three general categories:

    • Website safety: These extensions protect your data as you surf the web.

    • Ad and tracker blockers: The Chrome extensions here keep your browser free of annoying ads and invasive web trackers.

    • Password managers: These extensions help you secure your accounts with long and unique passwords.

    Website safety extensions

    Not all websites are safe. Some might harbor malware that will download to your device when you visit. Others might be phishing websites eager to trick you into entering sensitive personal data. And others may not be secure enough to protect you online.

    Each Chrome extension listed here protects your data and keeps you safe while browsing the web.

    AVG Online Security

    AVG Online Security is built by one of the best online security companies out there.

    • Blocks tracking cookies.

    • Flags unsafe websites.

    • Crowd-sourced feedback system improves security.

    Cons:

    Click&Clean keeps your browser free of clutter by deleting your browsing history every time you close Chrome.

    SiteJabber takes more of a Yelp-like approach to browser security, displaying reviews and ratings of every website you visit. It lets you see what its large community of online business reviewers thinks of each page: whether the website is safe, a scam, or simply lacking in security and privacy. 

    SiteJabber also uses a handy color-coded system to indicate the security of each web page you visit.

    Pros:

    • Color-coded system helps identify secure and unsecured websites.

    • Ratings appear beside each result when using a search engine.

    Cons:

    Pros:

    • Detailed user interface lets you control almost every aspect of browser privacy.

    Cons:

    • May take time to learn how to avoid breaking websites.

    Ad blockers and anti-tracking extensions

    Ads are annoying. They’re everywhere and pop up at incredibly inconvenient times. A lot of advertisers also use trackers to collect information about you to help them serve more relevant ads — but all this data can carry dire security and privacy issues.

    The extensions on this list block annoying ads and unwanted online tracking techniques to improve your browsing experience.

    Adblocker Ultimate

    • Automatically blocks all ads — plain and simple.

    • Free, open-source software lets anyone inspect it for security.

    Cons:

    • Pop-up notifications, like those showing the number of ads blocked, may be annoying (but you can disable notifications in Chrome).

    Disconnect

    Chrome’s Disconnect extension is an open-source anti-tracking extension that blocks trackers and shows you which trackers a website is using. The interface shows you how websites track the digital trail you leave while browsing, and you can choose which trackers to block or allow.

    • Works automatically upon installation.

    • Open-source software makes it easy to inspect the code for security.

    • User-friendly display lets you see different types of trackers.

    PixelBlock

    Some Chrome extensions offer targeted security for specific functions, and PixelBlock is one such specialist. PixelBlock blocks email trackers that people use to know when you open and read their emails.

    PixelBlock makes spotting these email trackers easy, with a little red-eye icon next to any email that tries to track you. Sometimes this information is identified, and other times it’s unknown, but you’ll always know which senders are trying to track you.

    Pros:

    • Works immediately upon installation.

    • The extension doesn’t track you or read your emails — it only monitors the senders.

    • A color-coded system tracks threat-levels as red, yellow, or green.

    Cons:

    • The local learning feature may be useful, but it’s not terribly secure — opt out for a more secure browsing experience.

    uBlock Origin

    uBlock Origin bills itself as more than just an ad blocker. It’s a broad content blocker that doesn’t clog up your browser and device memory. The extension uses a pre-set filter list to weed out ads and trackers.

    Pros:

    • Minimal effect on device performance.

    • Contains several pre-set filter lists and lets you create and choose your own.

    Cons:

    • Some features may be confusing for less tech-savvy folks.

    • Pre-set lists mean less flexibility in terms of which ads and trackers are blocked.

    Password manager extensions

    With so many online accounts to manage these days, it can be near impossible to keep track of your passwords, especially if yours are unique and complex.

    Thankfully, there are Chrome extensions that manage and even generate passwords for you, so you’re never locked out of your accounts and they’re always kept secure.

    Bitwarden

    More than just a secure password manager, Blur is an overall privacy-protection extension. It blocks trackers and masks your data, and generates, saves, and encrypts your passwords. Blur will mask your email address for free, but you need a subscription to hide your phone number and credit cards.

    Pros:

    • Free email masking and tracker blocking.

    Cons:

    Pros:

    • Security Dashboard shows your weak and reused passwords and recommends how to improve them.

    • Can generate strong passwords to replace weak ones.

    TeamPassword

    It’s one thing for one person to keep track of several passwords. It’s quite another for an entire team to do the same, with each member having their own passwords to manage.

    TeamPassword simplifies the password management process, using a cloud-based platform to manage multiple logins for teams. This extension is especially useful for businesses that have many employees and accounts to keep track of.

    Pros:
