URLColors

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

The only extension I could find that actually worked.

Great ! I always searched for that since colortabs was ko.

It is handy to separate and highlight test system tabs from production. Dead easy to use.

Plain, simple and very very useful regex would be nice 👍

Greet tool! Thank you :)

grateful for this extension.

This is great when working with multiple environments. Tip: you can customize border size/opacity per site, so you can set your prod instance to super visible bright red border to prevent you from making a career-limiting mistake!

Thank you. It helps me a lot.

I've been using URLColors for many years because it's simple and effective.
