opera:config ( Opera Preferences Editor – editor de configurações avançadas )

agosto 4, 2008

Assim como existe o about:config do Firefox e do Seamonkey, em que se pode ajustar manualmente e profundamente o browser, o Opera tambem tem esta opção e so digitar opera:config na barra de endereços ( ou clicar nos links da tabela abaixo), e um leque de opções aparecerão, aqui e terreno para muitas horas de testes, o Opera e o browser mais avançado que existe, muitos programadores o usam e o pessoal do software livre chora por ele nao ter seu codigo fonte aberto, o que é uma pena.
