The toolbar is completely free to download and use and has been developed by Family Historians for use by Family Historians.
As noted in the press release, "the range of links is especially strong for GB [Great Britian] and Irish research." It does, however, provide links to a number of primary U.S. sites.
Changes to the toolbar are made centrally, which means the toolbar developers control what is available, but the site currently offers over 170 links, which will be "expanded in response to user comments and suggestions." Users do have the ability to turn individual menus on and off and can also choose to add items from a selection of non-genealogy links.
