Features & Capabilities

SecurityShrimp APEX (Anti-Phishing EXtension) augments every page you visit with context-aware warnings that help you spot phishing attempts before you hand over a password.

It runs entirely in your browser. Nothing is sent to any server. No telemetry. No accounts. No data collection of any kind.

WHAT IT CHECKS

• Look-alike domains. paypa1.com, goog1e.com, arnazon.com, tvvitter.com — homoglyph tricks that fool a quick glance get flagged against the top 20,000 sites on the web.

• Unicode / IDN domains. Punycode-encoded URLs (xn--...) are decoded and shown so you can see what the address bar is actually rendering.

• Misleading link text. When a link reads "paypal.com" but actually points at evil.example, a warning appears on hover.

• Insecure connections. HTTP-only sites get a warning before you type anything sensitive.

• First-time visits. Sites you've never been to before are flagged so you can pause and verify the address bar before entering credentials.

HOW IT HELPS YOU RECOGNIZE FAMILIAR SITES

Every domain you visit is shown alongside a unique color and emoji fingerprint, derived locally from the domain name. Your bank, your email, your work tools — each gets a stable visual signature you'll start to recognize. If you ever land on a look-alike, the colors and the emoji will be different, even if the name looks right.

CONFIGURABLE TO HOW YOU WORK

• Show tooltips on every input, only on password fields, or never. • Whitelist specific sites or wildcards (paypal.com, *.google.com). • Toggle the misleading-link warnings independently.

PRIVACY

Everything happens on your machine. The extension uses your browser history (locally) to detect first-time visits, and downloads a public list of the top 20,000 domains once a week from Majestic to power the look-alike check. That list arrives bundled so the extension is useful from the first second after install.

Is SecurityShrimp APEX 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.

SecurityShrimp APEX requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

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