This guide will show you how to install an extension from a local file (such as .zip, .crx, or .xpi) in DuckDuckGo.
Currently, the DuckDuckGo browser does not support installing browser extensions of any kind.
Please check back for updates or refer to the official DuckDuckGo browser documentation for more information.
Tip: Always be careful when installing extensions from outside the official store. Only use files from trusted sources.
