Extension Metadata
About this extension
ContainerCookies gives you full visibility into cookies stored in each Firefox container — something the built-in DevTools don't show. View, copy, and
delete cookies from a single popup.
Features:
- Select any container from a dropdown (including "No container" for tabs opened outside containers)
- Cookies grouped by domain for easy browsing
- Expand any domain to see individual cookie names and values
- Copy a single cookie, all cookies of a domain, or every cookie in the container — all as JSON
- Click a cookie name or value to copy just that text
- Delete a single cookie with one click
- Delete all cookies for a specific domain
- Clear all cookies in a container at once
- Two-click confirmation on every destructive action so nothing gets wiped by accident
- Search by domain name or cookie name
Useful for anyone using Firefox Multi-Account Containers who wants to audit, clean up, debug cookie isolation, or extract cookies for use in scripts and
tools.
