DuckDuckGo Maps is a subscription-based addon for Firefox that enhances the mapping capabilities of DuckDuckGo searches. It addresses the issue of the maps button appearing inconsistently by providing a permanent button for easy access to mapping services. Users can choose between Google Maps and OpenStreetMaps based on their preferences, which is configurable in the settings. This addon is particularly useful for those who have transitioned to DuckDuckGo but miss the reliable mapping features typically offered by Google.

The addon is categorized under Internet & Network, specifically as a search and lookup tool, making it a valuable addition for users seeking a more seamless experience while searching for directions or locations. With its straightforward functionality, DuckDuckGo Maps ensures that users have quick access to mapping services without the frustration of navigating through occasional button appearances.
