commit 3a108a986e1e014399c3aad098b1586f4ecd5a9e
Author: Mike Perry <mikeperry-git at torproject.org>

    Omnibox: Add DDG, Startpage, Disconnect, Youtube, Twitter; remove Amazon, eBay, bing
    
    eBay and Amazon don't treat Tor users very well. Accounts often get locked and
    payments reversed.
    
    Also:
    Bug 16322: Update DuckDuckGo search engine
    
    We are replacing the clearnet URL with an onion service one (thanks to a
    patch by a cypherpunk) and are removing the duplicated DDG search
    engine. Duplicating DDG happend due to bug 1061736 where Mozilla
    included DDG itself into Firefox. Interestingly, this caused breaking
    the DDG search if JavaScript is disabled as the Mozilla engine, which
    gets loaded earlier, does not use the html version of the search page.
    Moreover, the Mozilla engine tracked where the users were searching from
    by adding a respective parameter to the search query. We got rid of that
    feature as well.
    
    Also:
    This fixes bug 20809: the DuckDuckGo team has changed its server-side
    code in a way that lets users with JavaScript enabled use the default
    landing page while those without JavaScript available get redirected
    directly to the non-JS page. We adapt the search engine URLs
    accordingly.
    
    Also fixes bug 29798 by making sure we only specify the Google search
    engine we actually ship an .xml file for.
    
    Also regression tests.
