A empresa Mozilla come\u00e7ou a aplicar um novo m\u00e9todo de identifica\u00e7\u00e3o de instala\u00e7\u00f5es do navegador. Nas vers\u00f5es distribu\u00eddas a partir do site oficial, fornecidas na forma de arquivos exe para a plataforma Windows, s\u00e3o inseridos identificadores dltoken, \u00fanicos para cada download. Consequentemente, fazer v\u00e1rios downloads sequenciais do arquivo de instala\u00e7\u00e3o para a mesma plataforma resulta em arquivos com diferentes somas de verifica\u00e7\u00e3o, uma vez que os identificadores s\u00e3o adicionados diretamente ao arquivo baixado. <\/p>\n

O efeito se manifesta apenas ao baixar arquivos exe a partir do ambiente Windows. Ao tentar baixar a partir do navegador ou do terminal no Linux, os arquivos exe sempre s\u00e3o os mesmos. Arquivos comprimidos que n\u00e3o est\u00e3o em formatos execut\u00e1veis tamb\u00e9m n\u00e3o s\u00e3o alterados. Afirmam que \u00e9 poss\u00edvel desativar a contagem do dltoken ao desligar a telemetria no navegador, mas n\u00e3o est\u00e1 claro como o controle da telemetria no Firefox ajudaria na instala\u00e7\u00e3o inicial e poderia influenciar a substitui\u00e7\u00e3o de dados durante o servidor<\/a>download de arquivos do site (o problema tamb\u00e9m ocorre ao baixar do Google Chrome). Como uma solu\u00e7\u00e3o alternativa para obter arquivos de instala\u00e7\u00e3o do Firefox sem identificadores, pode-se iniciar o download diretamente do site ftp.mozilla.org. <\/p>\n

A raz\u00e3o para a incorpora\u00e7\u00e3o do identificador dltoken \u00e9 o desejo de vincular as primeiras instala\u00e7\u00f5es, a telemetria existente e os identificadores do Google Analytics com os downloads reais do navegador. Em particular, isso permite avaliar as raz\u00f5es para varia\u00e7\u00f5es no n\u00famero de downloads e instala\u00e7\u00f5es, e entender quais instala\u00e7\u00f5es foram causadas por determinados downloads (por exemplo, \u00e9 poss\u00edvel descobrir que um arquivo baixado foi usado para instalar v\u00e1rias inst\u00e2ncias do navegador, o que explica por que um n\u00famero excessivo de instala\u00e7\u00f5es foi registrado em um dia, n\u00e3o correspondendo ao n\u00famero de downloads).
