A developer from Zambia crafted a currency converter browser extension to streamline online shopping. Frustrated by the tedious task of manually converting prices from international websites, the developer sought a more efficient solution. The extension, called Currency Converter Pro, allows users to simply hover over any price to see it instantly converted to their preferred currency, eliminating the need for multiple tabs and manual calculations.

The journey to create this extension provided valuable insights into web development. The developer had to tackle challenges such as detecting prices on complex websites like Amazon, where prices are split into multiple HTML elements. They also had to navigate the different APIs of Chrome, Safari, and Edge browsers, ultimately finding that Safari now supports the WebExtensions API, simplifying the development process.

The extension includes features like Pin Mode for comparing prices and a cyberpunk-themed tooltip for a futuristic user experience. The developer prioritized user privacy, ensuring no tracking or data collection. This product is a testament to the power of solving one's own problems, as the developer created a tool that is now useful for anyone dealing with multiple currencies.
