Tor 浏览器6.0.6及之后版本使用 DuckDuckGo 作为内置搜索引擎。 For a while now, Disconnect, which was formerly used in Tor Browser, has had no access to Google search results. Since Disconnect is more of a meta search engine, which allows users to choose between different search providers, it fell back to delivering Bing search results, which were basically unacceptable quality-wise.
