Features & Capabilities

Environment Marker is a versatile Chrome extension that lets you visually differentiate web pages by adding color-coded ribbons based on URL matching. Easily configure ribbons by specifying full or partial URLs, including support for RegExp patterns, enabling clear environment identification such as development, QA, or production sites.

Customize ribbon positions (top/bottom corners), sizes (from extra small to extra large), and labels to suit your needs. Additional features include multilingual support (English, Spanish, German, French, Simplified Chinese), a reusable color swatch of recently used colors, a tab counter that indicates active tab numbers with color cues, font selection from Google Fonts for ribbons, and even the ability to add colored markers to favicons. Import and export your ribbon configurations to maintain consistency across devices. Environment Marker enhances browsing clarity and workflow efficiency by visually tagging environments and sites distinctly.

Is Environment Marker 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.

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

Risk impact analysis details

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.

Environment Marker has earned a fairly good reputation and likely can be trusted.
