Firefox Container Selector

https://addons.mozilla.org/en-US/firefox/addon/container-forcer/

A Firefox extension that forces container selection for new tabs. When you open a page in a non-containerized tab, it will prompt you to select a container to continue browsing in.

Features

• Detects when you're browsing without a container
• Shows a user-friendly container selection interface
• Automatically reopens the current page in the selected container
• Displays container icons and colors for easy identification
• Doesn't interfere with already containerized tabs

Development Setup

1. Clone this repository:

git clone https://github.com/ledongthuc/firefox-force-container.git
cd firefox-force-container

2. Install the extension temporarily in Firefox:
   • Open Firefox
   • Navigate to about:debugging
   • Click "This Firefox" in the left sidebar
   • Click "Load Temporary Add-on"
   • Select any file in the extension directory
