## What it is
A small Chrome extension that monitors and optionally blocks network calls made by other browser extensions. It requires the extensions-on-chrome-urls flag to detect traffic from other extensions.

## Use cases
- monitor network requests made by other chrome extensions
- block extensions from making network calls
- audit browser extensions for suspicious network activity
- detect extensions that phone home
- investigate extension privacy and security

## When to choose
- you want visibility into what network traffic your installed extensions generate
- you want to block specific extensions from communicating over the network
- you are doing a security audit of your browser extensions

## When to avoid
- you need to monitor regular website traffic rather than extension traffic
- you cannot or do not want to enable the extensions-on-chrome-urls flag
- you need a general-purpose network sniffer or proxy
