@youdidnotknowme Quais configurações exatamente são essas? O meu mercado livre nao faz login de jeito nenhum. Fica carregando eternamente. Ja desinstalei, fiz a instalação limpa, sem extensões e dados de usuario mas mesmo assim o problema persiste. Nos outros navegadores funciona normalmente...

No
I unistalled Opera and Installed again. Worked for a time, but the problem is back. I'm only able to upload with VPN. While I'm using Dropbox, appears a server error while im uploading.

@leocg And how can I solve it? It only happens with Opera...

I can't upload files on websites, like Facebook, Dropbox, Gmail,etc. When I try it, it starts uploading and shows a error. I'm only able to send files when I activate the Opera VPN, so I believe its a config error. Someone can help me? It happens for a long time and only with Opera.

I'm using the version 70.0.3728.189
