Features & Capabilities

Never confuse production and development again.

EnvGuard makes your environments instantly recognizable, helping prevent accidental testing, changes, or destructive actions in the wrong environment.

Every website you visit is automatically checked against the environment rules you define and clearly marked:

🔴 Production - a prominent red banner across the page that's hard to miss
🟡 Development - a striped border around the page
🧰 Toolbar badge - shows P or D, so you can identify the environment even when the popup is closed

Whether you're switching between production and development, staging and live, or multiple client environments throughout the day, EnvGuard gives you an immediate visual reminder of where you are before you click, submit, deploy, or delete anything.

Privacy first

All environment rules and settings are stored locally on your device. Nothing is sent to external servers.

Open source

EnvGuard is fully open source, so you can inspect the code, contribute improvements, or build it yourself.

Built for developers and QA

EnvGuard is designed for developers, QA testers, system administrators, and anyone who regularly works across multiple environments and wants an extra layer of protection against costly mistakes.

Is EnvGuard 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.

EnvGuard 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.

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