I am working on a Firefox extension for search aggregation. It currently works with DuckDuckGo, Wikipedia, Stack Overflow, Reddit, and others. The idea is that for 80% of my searches I can find the answer on Wikipedia or Stack Overflow, removing the need for a general search engine such as DuckDuckGo or Google, and thus hopefully avoiding blogspam and tracking to some extent. Extraction works through XPath, and I am trying to make it easier to add new engines without looking at the HTML.

Unfortunately, it currently looks terrible, and so far has received one 1-star review, which is not doing much to help my motivation.

It's on the Firefox add-on store (https://addons.mozilla.org/en-US/firefox/addon/metasearch). I plan to add the code on Github once I refactor it some more and add support for Chrome.
