Features & Capabilities

Magnetar Guardian Stay focused, stay safe, stay in control. Magnetar Guardian is a local browser protection extension that helps you decide what the web is allowed to put in front of you. Pick the categories you want to keep out of your day, including adult content, gambling, social sites, dating, drugs, violence, anonymising proxies, phishing, malware, and scams, and Guardian blocks them at the network level before pages start loading. SafeSearch is enforced automatically on Google, Bing, DuckDuckGo, Ecosia, and YouTube, so the protection extends to search results as well as direct navigation. A PIN-locked dashboard protects every setting, category toggle, and site allowance. When you need a trusted exception, the new unified Guardian toolbar handles it cleanly. Unlock with your PIN, and a persistent temporary-access toolbar appears, stays visible across navigation, and can be dragged anywhere on the page without being lost off-screen. Page clicks outside the toolbar pass through normally, so browsing continues uninterrupted. When you are done, one tap resumes protection. Version 2.0.0 is a major interface and behaviour update focused on a calmer, clearer, more consistent experience. The blocked page has been redesigned with better information about the site, the reason, the status, review actions, coverage, and recent activity. Search keyword protection now respects your category settings, so turning a category off also turns off the matching keyword filters. The expanded toolbar uses a cleaner three-column layout, recent activity is limited to the last four limited sites, and the protection wording has been refined throughout. Privacy and security Guardian is built to stay out of your business. No analytics, no tracking scripts, no accounts, no remote logging, no browsing-history upload. Settings, statistics, review requests, PIN state, and protection state live in your browser only. Your PIN is stored as a secure hash, never in plain text. Filtering logic and rules are bundled with the extension, so no remote code is loaded or executed. What you get

Category blocking for adult, gambling, social, dating, drugs, violence, proxy, phishing, malware, and scams SafeSearch enforcement on Google, Bing, DuckDuckGo, Ecosia, and YouTube PIN-locked settings and per-site allowances Movable, persistent temporary-access toolbar with auto-relock Redesigned blocked page with full protection context Local-only storage, no account, no tracking, no data leaves your device

Version 2.0.0 is the new baseline Guardian release for Firefox.

Is Magnetar Guardian Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Magnetar Guardian requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Magnetar Guardian is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
