问题描述

在Ubuntu 14.04中，当我使用地址栏或搜索栏在Firefox中进行搜索时，系统始终将t=canonical添加到我的搜索中。因此完整的字符串变为：https://duckduckgo.com/?q=cat+cooking+salmon&t=canonical。

但是，如果我直接进入搜索引擎来执行相同的搜索，即键入搜索引擎名称并从显示的搜索框中进行搜索，则不会发生这种情况。在这种情况下，字符串为：https://duckduckgo.com/?q=cat+cooking+salmon。

如何阻止Ubuntu /Firefox将t=canonical添加到我的搜索查询中？而且，为什么这种行为首先存在？

最佳方案

&t=

Through partnerships with developers and companies, DuckDuckGo has been integrated into many applications. In these partnerships, a portion of DuckDuckGo’s advertising revenue is sometimes shared back. To assign advertising revenue and collect anonymous aggregate usage information, developers add a unique “&t=” parameter to searches made through their applications.

If you want to remove it, edit the file:

/usr/lib/firefox/distribution/searchplugins/locale/*language-here*

Edit all the languages just to be sure.

至于为什么，Canonical可能会赚一些钱，但这仅仅是猜测。
