!EndPointX

> A Firefox-first, local-only WebExtension for mapping endpoint URLs from the
> active tab during authorized security review.

EndPointX helps security testers, bug bounty researchers,
de, and defenders quickly turn the currently open page into a compact
endpoint in. It collects URLs from page structure and browser
resource timing metadata, redacts query , deduplicates endpoints, and
exports a local JSON artifact.

It is intentionally not a proxy, crawler, fuzzer, scanner, exploit tool, or
request replayer.

Status

Prototype: 0.1.0

The first release is an unpacked Firefox extension for local de and
review. A de zip is attached to GitHub releases. It is not listed on
Mozilla Add-ons yet.

Lawful Use Only

Use this tool only on systems you own, systems you administer, explicit bug
bounty scope, written client scope, or local lab targets.

This project is designed for:

This project is not designed for unauthorized reconnaissance or automated
probing of third-party systems.

Security Warning

Use only on systems and content you own or are explicitly authorized to test.
Unauthorized use may policy, law, or both.

Disclaimer

To the maximum extent permitted by law, this software is provided "as is"
without warranties of any kind. The authors and contributors are not liable
for misuse, unauthorized use, or any loss or damage resulting from use of the
software.

What It Collects

Collection happens only after the user clicks Collect Current Tab in the
extension popup.

The collector records:

The latest capture is stored in Firefox extension storage so the popup can be
closed and reopened without losing the current map.

What It Does Not Collect

Why This Exists

Most security workflows e need a clean list of obser,
assets, forms, and API-looking URLs. Browser de can show this, but the
output is scattered across Elements, Network, Sources, and manual notes.

EndPointX makes a narrow promise:

1. Ask the active tab what endpoint-like URLs are .
2. Redact risky URL .
3. Deduplicate the result.
4. Keep it local.
5. Export a useful artifact for notes and reports.

Features

Permissions

The extension follows Mozilla's WebExtension permission model and keeps the
permission set small.

| Permission | Why it is used | Boundary |
| --- | --- | --- |
| activeTab | Grants temporary access to the current tab after user action. | Current active tab only. |
| scripting | Injects the collector script on demand. | One-shot execution from the popup. |
| storage | Saves the latest capture locally. | Firefox extension storage only. |

Permissions intentionally not requested:

The manifest also declares Firefox's data_collection_permissions.required as
["none"]. The extension does not transmit collected data outside the local
browser.

Installation

Temporary Firefox Install

1. Open Firefox.
2. Visit about:debugging.
3. Select This Firefox.
4. Select Load Temporary Add-on.
5. Choose manifest.json from this folder.

Firefox keeps temporary extensions installed until the browser is restarted.

De With web-ext

Mozilla's official web-ext workflow can lint and run the extension:

The scripts use npx --yes web-ext ..., so no committed dependency folder is
required.

Usage

1. Na to an authorized target page.
2. Click the EndPointX toolbar icon.
3. Click Collect Current Tab.
4. Review the endpoint list and origin labels.
5. Use the filter box to narrow the list.
6. Click Copy URLs to copy the currently endpoints, or Export JSON to save the full capture.

For a local smoke test, load the extension temporarily and collect endpoints
from Seedboard:

The smoke test is local-only and keeps the collection flow inside the browser.

Output Format

Example export:

Security And Privacy Model

EndPointX is built around a narrow collection surface:

See PRIVACY.md and SECURITY.md for the full policy.

When web-ext is a, also run:

Mozilla recommends web-ext lint before running or submitting an extension.

Project Layout

Design Choices

No webRequest In The MVP

webRequest is powerful, but it expands the permission story and can move a
small endpoint mapper toward proxy-like behavior. The M on acti
DOM inspection and browser Performance API metadata instead.

Future may add optional network obser only after the scope guard,
redaction model, and permission explanation are stronger.

No Broad Host Permissions

Mozilla documents activeTab as a way to let an extension act on the current
page after explicit user interaction without requesting broad host access. This
matches the product boundary: collect only when asked.

Redacted URLs By Default

Endpoint mapping usually needs paths and parameter names, not li
. Query are replaced with <redacted> before display, storage, or
export.
