Website color coding Firefox

Website color coding

Helps to identify which environment you are working in.

Features & Capabilities

Need to keep track of what environment you are working in? Then this extension is for you! But how, you ask? Let me explain.

Basically, what this extension does is adding some basic HTML elements to your loaded page to help you identify the environment you are working in.

But how does it work?! There are two ways that environments are detected:

Firstly, by a blanket match of domain names via regular expressions. Going by the default configuration this means that any site you visit that starts with "test." is getting elements added that show you a blue border at the top, and a message at the bottom right saying "Test environment". You can change the matching through the options page.

Secondly, you can specifically assign a domain to an environment by selecting it from the popup menu which you can access by clicking the extension's icon in your browser.

There are quite some options to modify the way you want to see the visual feedback of the environment you are working in. Colorbars can be set on each direction of your page, and the message telling you what environment you are in can be positioned in any corner or border (and rotated if you like).

Oh.. one more nice feature: if a site is detected as being in one of your environments, it will give you a warning if the domain (hostname) will be changed. That will help you with those pesky links on a development site that sneakily directs you to the production site!

Is Website color coding 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.

Website color coding 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.

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