Fastpath од gabesullice

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 (Shift+Alt+U) to copy /products/123?view=details
3. Navigate to https://production.example.com
4. Click Paste Path (Shift+Alt+I) to go to https://production.example.com/products/123?view=details

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

Paste Path will also strip https://example.com from https://example.com/destination, which means you can copy any link as usual and use it with Fastpath.
