Search Web Sites In Firefox Web Browser
You can use the site: parameter in search engines like Google, Bing or Yahoo to search only a specific website. The site:ghacks.net firefox command for example displays all Ghacks pages that refer to the Firefox web browser that the search engine has indexed.
The listing of pages does not necessarily have to be complete as search engines return only what they have indexed and not necessarily what is published on the site in question.
You can use the command to narrow down search results to a single domain. This can be useful if you only want to search that specific site, say to find articles about something on Wikipedia, items on eBay or Amazon, or phone numbers on Microsoft's website.
The parameter uses the same syntax on all major search engines. Use site:domain searchterm and replace domain with the domain name of the site you want searched, e.g. wikipedia.org, and searchterm with what you are interested in.
Update: Note that Search Site is no longer compatible with recent versions of the Firefox web browser. You may use Search Site WE instead by the same author which is compatible with Firefox 57 and newer versions of the browser.
Firefox add-on Search Site
The Firefox add-on Search Site makes the search parameter more accessible by providing direct access to it. Once installed in Firefox, you can use it to search for selected text on the site you are on.
So, if you are here on the site and notice something of interest, say the term Windows 8, you can highlight it, right-click the selection and use the search site context menu item to search only on this site for that term.
The Search Site extension for the Firefox web browser provides two options to access the site search parameter.
The first is by highlighting text on a website, right-clicking and selecting the "search entire site" or "search subdomain" options in the context menu. This will open a new tab in Firefox that displays the results of a site: parameter search in the default search engine of the browser.
Changing the default search engine has a direct effect on this function, which means that this method is always using the default browser search engine.
The extension is therefor not limited to Google (the default search engine) but can be used in conjunction with any other search engine supporting the site parameter.
The second option is to click on the site search button that has been added to the main toolbar. Activation displays a search field to search for any term on the entire site or the current subdomain.
Site Search is a handy browser extension for the Firefox web browser to run site: searches on the current domain without having to open a search engine in a new tab.Advertisement
