Yes, Mozilla Firefox is compatible with extensions and add-ons, which enhance the browsing experience by adding new features and functionality. The platform has a robust ecosystem of add-ons available through the official Mozilla Add-ons website. Users can browse, install, and manage add-ons that cater to their unique needs, whether they are looking for tools for productivity, security, or customization of the browsing interface. Firefox supports both WebExtensions, which are compatible with many modern browsers, and legacy add-ons, although support for the latter is being gradually phased out in favor of the more secure and performance-optimized WebExtensions. This commitment to extension support allows users to tailor their browsing experience effectively. For more detailed information about specific extensions or how to use them, one may consider visiting the Mozilla Add-ons website.
