Automatic browser search provider detection and usage

One or more computer-readable storage memories storing instructions that, when executed by a computing device, cause the computing device to perform operations, the operations comprising:

• obtaining, via a browser, input requesting web content;
• in response to obtaining the input, accessing the web content and receiving mark-up language code that describes the web content for presentation by the browser, the mark-up language code including references to one or more search providers usable by the browser for searches, the references including attributes that specify the one or more search providers;
• in response to receiving the mark-up language code, identifying the one or more search providers by detecting the references included in the mark-up language code;
• generating a list from which a search provider for conducting the searches is selectable from the identified search providers, the list being generated using the attributes included in the references;
• and
• exposing the list of identified search providers using the references within the mark-up language of the web content, individual search providers of the list are selectable via the list to cause a search component of the browser to perform a search using a selected one of the search providers.

A computing device comprising:

• one or more processors;
• one or more computer-readable media storing instructions executable via the one or more processors to implement a browser configured to perform operations comprising:
• receiving, via a tab of the browser, an input requesting web content to be loaded in that tab of the browser;
• in response to receiving the input, receiving mark-up language code that describes the requested web content for presentation in that tab of the browser, the mark-up language code including references to one or more search providers usable by that tab of the browser for searches, the references including attributes that specify the one or more search providers usable in that tab of the browser;
• in response to receiving the mark-up language code, identifying the one or more search providers by detecting the references included in the mark-up language code;
• generating a list from which a search provider for conducting the searches in that tab of the browser is selectable from the identified search providers, the list being generated using the attributes included in the references;
• exposing the list of identified search providers using the references within the mark-up language of the web content and the previously browsed web content.
