Como é que o compiz sabe / se preocupa com pesquisas no firefox?

Question

Enquanto observava a saída de journalctl -f , notei que aparentemente compiz é notificado sobre (e logs) todas as pesquisas que faço na barra de entrada (ou na barra de pesquisa) do Firefox (mas não em Chromium ).

Digitando na barra de entrada algo como

resulta nas seguintes linhas no meu log

Não importa qual provedor de pesquisa eu tenha selecionado. Gostaria de saber quais configurações causam esse comportamento do compiz e como evitar isso.

_{Na minha opinião, não é da conta do compiz que escrevo uma barra de pesquisa no meu navegador.}

Eu sei que é possível contornar isso inserindo expressões de pesquisa diretamente no campo de pesquisa de qualquer provedor de pesquisa, mas não é isso que eu estou procurando.

Após uma pesquisa adicional, encontrei as seguintes linhas adicionais no meu log (após o login):
