There are two primary places where default sets of domains are used: URLBar +domain auto-completion, and Top Sites suggested thumbnails. + +The source of these domains is typically the Alexa top sites lists, global and by-country. Before +shipping the sets of domains, the lists are sanitized. + +Domain Auto-completion +====================== + +As you type in the URLBar, Firefox will scan your history and auto-complete previously visited +domains that match what you have entered. This can make navigating to web sites faster because it +can avoid significant amounts of typing. During your first few uses, Firefox does not have any +history and you are forced to type full URLs. Shipping a set of top domains provides a fallback. + +The top domains list can be localized, but Firefox will fallback to using en-US as the default for all +locales that do not provide a specific set. The list can have several hundred domains, but due to +size concerns, is usually capped to five hundred or less. + +Sanitizing Methods +------------------ + +After getting a source list, e.g. Alexa top global sites, we apply some simple guidelines to the +list of domains: + + +* Remove any sites in the Alexa adult site list. +* Remove any locale-specific domain duplicates. We assume primary URLs (.com) will redirect to the + correct locale (.co.jp) at run-time. +* Remove any explicit adult content* domains. +* Remove any sites that use explicit or adult advertising*. +* Remove any URL shorteners and redirecters. +* Remove any content/CDN domains. Some sites use separate domains to store images and other static content. +* Remove any sites primarily used for advertising or management of advertising. +* Remove any sites that fail to load in mobile browsers. +* Remove any time/date specific sites that may have appeared on the list due to seasonal spikes. + +Suggested Sites +=============== + +Suggested sites are default thumbnails, displayed on the Top Sites home panel. A suggested site +consists of a title, thumbnail image, background color and URL. Multiple images are usually +required to handle the variety of device DPIs. + +Suggested sites can be localized, but Firefox will fallback to using en-US as the default for all +locales that do not provide a specific set. The list is usually small, with perhaps fewer than ten +sites. + +Sanitizing Methods +------------------ + +After getting a source list, e.g. Alexa top global sites, we apply some simple guidelines to the +list of domains: + +* Remove pure search engines. We handle search engines differently and don't consider them to be + suggested sites. +* Remove any locale-specific domain duplicates. We assume primary URLs (.com) will redirect to the + correct locale (.co.jp) at run-time. +* Remove any explicit adult content domains. +* Remove any sites that use explicit or adult advertising. +* Remove any URL shorteners and redirecters. +* Remove any content/CDN domains. Some sites use separate domains to store images and other static + content. + +Guidelines for Adult Content +============================ + +Generally the Adult category includes sites whose dominant theme is either: + +* To appeal to the prurient interest in sex without any serious literary, artistic, political, or + scientific value +* The depiction or description of nudity, including sexual or excretory activities or organs in a + lascivious way +* The depiction or description of sexually explicit conduct in a lascivious way (e.g. for + entertainment purposes) + +For a more complete definition and guidelines of adult content, use the full DMOZ guidelines at +http://www.dmoz.org/docs/en/guidelines/adult/general.html. + +Updating Lists +============== + +After approximately every two releases, Product (with Legal) will review current lists and +sanitizing methods, and update the lists accordingly. |
