Good browser security combines two habits: blocking trackers and unwanted content, and never reusing weak passwords across sites. A content blocker cuts down on tracking scripts and intrusive ads, while a password manager generates and stores unique logins, which removes the biggest single risk to your accounts.
Blocking ads and trackers
uBlock Origin Lite blocks most ads and known tracking scripts using Chrome's Manifest V3 rules system. It's lightweight and doesn't need a large custom filter list to work well, making it a solid default for most people who want fewer ads and less tracking without configuring anything.
Managing passwords securely
Bitwarden is a freemium, open-source password manager that generates strong unique passwords and autofills them across sites. 1Password is a paid alternative built for families and teams, adding shared vaults and admin controls. Either beats reusing the same password across multiple accounts.
What permissions security extensions need
Content blockers need to read and modify web page content to block ads and trackers, which is expected for their job. Password managers need to read login forms to autofill credentials. Review permissions for any extension outside these categories that requests similar access, since it's a common way malicious extensions steal data.
