DuckDuckGo Plus, a Mozilla Firefox add-on developed by DuckDuckGo that implements a safe search function for your browser, is now at version 0.2.43.
The advantage of the DuckDuckGo engine is that it doesn't track anyone, which serves to better protect users’ privacy.
The add-on will implement a DuckDuckGo toolbar button that will provide easy access to the options, will add DuckDuckGo as the default search engine through the address bar, search bar and context right-click menu, and will provide DuckDuckGo instant answers on Google and Bing.
Downoad DuckDuckGo Plus 0.2.43 right now from Softpedia. This is a restartless add-on and will become active on the fly.
