Exato
Penso extensões como uma nova via de vulnerabilidade que se adiciona ao browser também (que provavelmente é a aplicação mais perigosa rodando no computador)
Então se posso simplificar o processo não tenho dúvidas e simplifico.
Melhor assim
Eu Concordo.
Ao mesmo tempo, existem algumas extensoes que adicionam segurança
por exemplo , uBlock e HTTPSEverywhere. Um bom bloqueador de ads é essential, poisevita até phising. E https tb é obrigatório hoje em dia
Mas essas extensors tipo stylish acho bobo . Muitas ainda são uma janela de vulnerabilidade mesmo.
Eu vi que é possível utilizar o Firefox para mudar o CSS da página, clicando o botão direito > Inspect > Style Editor.
Lá é só colar o CSS que você quiser no style.css é pronto, o site fica preto. Cola esse aqui como exemplo:
