Features & Capabilities

Stop Guessing Which Environment Is Open

Environment Favicon Switcher makes development, review, staging, sandbox, and production tabs instantly recognizable.

No more opening the wrong tab, editing production by mistake, or searching through identical favicons.

Clear Visual Indicators:

Custom favicons
Colored toolbar badges
Optional title prefixes such as [DEV], [STAGING], or [PROD]
Automatic updates during single-page application navigation

Powerful URL Matching:

Create precise rules using:

Domains and subdomains
URL text
Glob patterns
Regular expressions
Exclusion patterns
Explicit priorities

When several rules match, conflicts are resolved predictably. The built-in URL tester shows exactly which rule wins and why.

Built for Real Development Workflows

Use it with:

Local development servers
Pull request and preview deployments
Test, sandbox, and UAT environments
Staging applications
Production websites
Multi-project and multi-team setups

Organize rules into groups, duplicate configurations, reorder priorities, or temporarily disable environments without deleting them.

Use Your Own Visual Identity:

Choose from built-in icons, generated favicons, imported images, remote HTTPS images, or the website’s original favicon.
You can keep production branding untouched while still displaying a clear badge or title prefix.

Import, Export, and Sync:

Export your configuration as JSON for backups or team sharing.
Settings are stored locally by default. Optional browser synchronization lets you reuse the same configuration across profiles or devices.

Privacy First:

No analytics. No ads. No tracking. No telemetry. No developer-operated backend. No remotely hosted executable code.

Make every environment unmistakable before you click, test, edit, or deploy.

Is Environment Favicon Switcher 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 Favicon Switcher 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.

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