Multi-Product Comparator

About

Multi-Product Comparator highlights shops that carry all your selected products on price comparison sites.

When shopping for multiple items, it's hard to find a single shop that stocks everything. This extension solves that:

1. Visit a product page and click "Add to Compare"
2. Navigate to another product page
3. Shops carrying all your added items are highlighted

Features:
- Floating panel to manage your product list directly on the page
- Works across idealo (de, at, fr, es, it, co.uk), Geizhals (de, at, eu), Skinflint, Cenowarka, billiger.de, and guenstiger.de
- Localized UI matching each domain's language
- Session-based storage — your list clears when the browser closes
- Lightweight, no tracking, no external requests
