URLColors: Visual Environment Flags for Browsing

"URLColors" is a Chrome extension designed to help users, especially web developers, differentiate between various environments such as development, testing, or production. It flags websites by adding a customizable, colored border that can blink, based on user-defined keywords in the URL. This visual cue helps prevent accidental operations on the wrong platform.

Extension summary

This extension allows you to flag specified websites by highlighting the website with a custom colored border. This is especially useful for developers who run their web applications on many different environments and who are constantly switching between a dev, test, and production version of an app or database. Because the application may look the same on all environments, it's easy to accidentally do something on the production environment that shouldn't have been done.

With URL Colors, you can easily have the browser flag important websites for you by specifying a the keyword to match against the tab url, the border color, width, opacity, whether or not the border should blink, and the interval of blinking. The wildcard character (*) is now supported.

It also has a demo mode, or snooze mode, so you can shut if off while presenting for a specified period of time, without worrying about reactivating it later. It automatically turns back on for you!

I am loving this extension. :) however I have a question: how can I set the border width without specifying the flash and timer properties?
