ZIP Reader is a Firefox add-on designed specifically for unzipping compressed files with ease. Users can simply drag and drop a zipped file into the designated area of the application UI, where all contents will be displayed. The interface allows for convenient downloading of individual files or all files at once into a single folder. This tool is solely focused on reading ZIP files, meaning that users looking to create ZIP archives will need to seek alternative software.

The add-on features a reload button to refresh the app interface, ensuring users can easily access the latest updates after each unzip operation. It’s important to note that ZIP Reader processes files one at a time, so multiple extractions should be handled sequentially. Utilizing an open-source JavaScript library for its functionality, this add-on provides a straightforward solution for managing ZIP files within the Firefox browser.
