Que informações o Autocopy do complemento do Firefox coleta?

Question

Eu tenho usado o Autocopy do Firefox há anos sem reclamar no Kubuntu. Eu só notei ontem que, desde a versão 1.0.6.1, assinada a partir do final de 2012, ele possui um software de rastreamento da WIPS (veja o histórico de versões ). Ao descobrir este problema, eu desinstalei o add-on e o substituímos por um autocopy 2 semelhante, mas livre de WIPS. / a>.

Depois de baixar e extrair o XPI mais recente, descobri que os arquivos JavaScript wips.js e wipstats.js estão incluídos em todas as páginas que abro no Firefox; para ser mais específico, um ouvinte de evento executa o wips.init (na parte inferior do wips.js) em cada evento de carregamento.

Alguém com algum conhecimento de JavaScript pode me dizer quais informações são coletadas e enviadas para o WIPS por wips.init? É o script registrando apenas o uso do complemento e atribuindo-me um GUID? Ou há algo mais? Em particular, o script WIPS está enviando dados como meu histórico de navegação, dados de formulários ou senhas?

Aqui o código fonte para wips.js:
