Browser extensions are one of the most underutilized tools in a parent's digital safety toolkit. The right combination of extensions can block ad trackers, filter harmful content, manage passwords securely, and give you meaningful oversight of what your child encounters online — often for free.
Ad and Tracker Blockers
Ad blocking extensions do more than remove ads — they block the tracking scripts that follow your child across the web and build detailed behavioral profiles. uBlock Origin (available for Chrome and Firefox) is the most widely recommended option for its effectiveness and low system overhead. On Safari, 1Blocker provides similar functionality. These extensions meaningfully reduce the data footprint your child leaves as they browse.
Password Managers
If your child uses the same password across multiple sites — which most teens do — a single breached account can compromise every account. A family password manager (options include Bitwarden, which is free and open-source, and 1Password, which offers family plans) generates and stores unique, complex passwords for every site. Installing this as a browser extension makes it easy enough that your child will actually use it.
Content Filters
Browser-based content filters can block categories of harmful content at the DNS or extension level. These work differently from platform moderation — they apply across all websites, not just a single platform's content. Options like CleanBrowsing Family DNS or browser extensions with category filtering can provide a consistent baseline of protection regardless of which site your child visits.
Setting Expectations
Extensions are tools, not substitutes for parental involvement. The most important conversation to have alongside installing these tools is a direct one: "I'm putting these in place to protect you, not to spy on you. If something online ever makes you feel uncomfortable, I want you to tell me." The tools work best when paired with trust.
