Fastpath: URL Path Copier

A simple Firefox add-on that copies and pastes URL paths between tabs, ignoring or preserving the tab's origin (i.e., its scheme, host, and port).

Use Case

When you need to visit the same path on different domains or ports. For example:

1. You're on https://staging.example.com/products/123?view=details
2. Click Copy Path to copy /products/123?view=details
3. Navigate to https://production.example.com
4. Click Paste Path to go to https://production.example.com/products/123?view=details

Installation

Installation

Install from the Firefox Add-ons page.

Temporary Installation (for development)

1. Open Firefox and navigate to about:debugging
2. Click "This Firefox" in the left sidebar
3. Click "Load Temporary Add-on..."
4. Select the manifest.json file from this directory

Usage

Click the extension icon in your toolbar to reveal two buttons:

• Copy Path — Copies the current tab's path, query string, and fragment (everything after the host)
• Paste Path — Reads the clipboard and navigates to that path on the current tab's origin

Keyboard Shortcuts

You can also use keyboard shortcuts instead of the popup:

• Alt+Shift+U — Copy URL Path
• Alt+Shift+I — Paste Into Path

These shortcuts can be customized in Firefox via about:addons → gear icon → Manage Extension Shortcuts.

Permissions

• activeTab — Access the current tab's URL
• clipboardWrite — Copy the path to clipboard
• clipboardRead — Read the path from clipboard
