## Description

**Containers Theme** is a Firefox extension that changes your browser window theme to match the color of the active container tab. This enhancement helps increase the visibility of normal containers, making it easier to distinguish different browsing contexts. Although there is currently a known bug in Firefox that affects the use of pastel colors, causing brighter shades, a fix is expected soon.

By providing a seamless color coordination between the active container and the browser theme, Containers Theme offers an intuitive and visually organized browsing experience, perfect for users who leverage Firefox's Multi-Account Containers extension to separate work, personal, and other activities.
