AmznShipWarn

AmznShipWarn is a lightweight browser extension that alerts you whenever an item on Amazon is not shipped directly by Amazon. Designed to help users avoid unexpected shipping costs or third-party sellers, it works across multiple Amazon domains and integrates seamlessly into both Firefox and Chromium-based browsers.

How to install

Firefox 🦊

For Firefox, you can directly get the extension from the official Add-On page.
Also works on Firefox for Android™

Chrome 🔵🔴🟡🟢

For Google Chrome (and most Chromium-based browsers), you can get the extension from the official Chrome Web Store.

Note: If you use a chromium based browser, but don't want to use the official Chrome Web Store, yo can still install the extension manually:

1. Download the .zip from the latest release
2. In Chrome, go to chrome://extensions/ and enable Developer Mode
3. Drag and drop the .zip file into the Chrome window

You won't get automatic updates, but you can watch this repository to get notified about new releases.

How does it work?

The extension checks the page for the text that holds the shipping information. If the text contains the word "Amazon", the extension does nothing. If the text does not contain the word "Amazon", the extension adds a warning to the page. In order to get the user's attention and make them aware of potential shipping costs.
