Amazon Assistant for Firefox was a free browser extension designed to enhance the online shopping experience by helping users compare prices, track orders, and find deals. It integrated seamlessly with the Firefox browser, allowing users to access their Amazon account and receive personalized recommendations directly while browsing other websites. Key features included price tracking, wish lists, and a streamlined checkout process, which aimed to simplify shopping across multiple platforms.

However, as of March 28, 2023, Amazon has officially discontinued the Amazon Assistant for Firefox. Users can no longer utilize the extension, but they will retain access to any lists created and products added from other sites. This decision reflects Amazon's ongoing evaluation of its product offerings, and while it may cause some inconvenience, the core functionalities related to user lists and product management remain accessible through the main Amazon platform.
