## Description

Containers with Transitions is an advanced fork of the popular Multi-Account Containers Firefox add-on. It empowers users to create and maintain browsing containers with added "container transition rules," allowing you to specify which container a page should open in based on the container from which it was opened. This functionality enhances compartmentalization of your web browsing for privacy, organization, and efficiency.

The extension reduces unwanted prompts and streamlines tab management by intercepting clicks and managing container transitions smoothly. Users can define domain-specific and default rules for container transitions, ensuring that related sites open in the correct browsing context automatically. Key improvements include eliminating repeated confirmation screens when opening related tabs and enhancing middle-click handling within websites.

Ideal for users seeking refined control over browsing contexts, Containers with Transitions is recommended as a replacement for the original Multi-Account Containers add-on to avoid conflicts. It offers an improved, flexible browsing experience suited for multitasking, privacy segmentation, and workflow organization.
