![]() ![]() Sidewiki is currently available for Internet Explorer and Firefox through Google Toolbar, the Google Chrome browser through an add-on, and for other browsers, like Safari, it was available as a bookmarklet. Web site owners could not control Sidewiki comments, and there was no way for a web site to opt out of Sidewiki however, Sidewiki was disabled on secure sites. ![]() In September 2011, Google announced that it would discontinue Sidewiki. My Location was a geolocation service which uses the location of Wi-Fi access points to determine the toolbar user's location. This location was used to optimize search results based on where the user was located. Google Toolbar can also provide the geolocation data to third-party websites through the W3C Geolocation API. Google Toolbar was criticized when the AutoLink feature was added to the toolbar because this new feature directed users to pre-selected commercial websites. Google said that the feature "adds useful links" and "none of the companies which received AutoLinks had paid for the service." For example, if it finds a book's ISBN on a webpage, it provides a link to Amazon's product page for the particular book. The desktop version of Google Toolbar shows the cached copy of any given search result, which was useful for slower Internet connections and benefitted by Google Web Accelerator until its discontinuation in 2008. This feature does not exist for the mobile version. Google Watch has raised concerns about Google Toolbar's possible threats to privacy, such as tracking of browsing patterns, automatic installation of updates without the user's knowledge, and a privacy policy that can be revised without notice. The toolbar does not track personally identifiable surfing activities of the end user unless advanced features such as PageRank are specifically enabled by the user. ![]()
