Best Chrome Extensions for Privacy & Security in 2026
Protect your privacy online with these essential Chrome extensions. Block trackers, manage passwords, and browse safely.
Your browser knows more about you than your best friend. Every site you visit, every form you fill, every ad you see — it's all tracked. These Chrome extensions fight back.
1. uBlock Origin
The most efficient content blocker available. Not just an "ad blocker" — uBlock Origin blocks ads, trackers, malware domains, and more using community-maintained filter lists. It uses significantly less memory than alternatives like Adblock Plus.
The numbers: 16M+ users, 4.7/5 rating. The community trusts it for a reason.
Why not Adblock Plus? uBlock Origin is open source, uses less memory, and doesn't have an "acceptable ads" program that lets advertisers pay to bypass the blocker.

2. Bitwarden
An open-source password manager that's actually good. Generate strong passwords, autofill logins, and sync across all devices. The free tier is more generous than most paid competitors.
Why not LastPass? Bitwarden is open source, has never had a major breach, and the free tier includes unlimited passwords across unlimited devices.

3. Privacy Badger
Built by the Electronic Frontier Foundation (EFF), Privacy Badger automatically learns to block invisible trackers. Unlike traditional blockers that use filter lists, Privacy Badger uses algorithmic detection — it watches which domains track you across sites and blocks them.
What makes it unique: It learns as you browse. The more you use it, the better it gets.
