i used a link from BB: https://seg.bb.com.br/extras/corrige.html And it solved the problem, hope not just temporally.

Did not work. will try to contact: Banco do Brasil 4004-0001 ou 0800-729-0001

Nope. I got feedback from Banco do Brasil, and they say to me they are studing the case, but they had an issue with Firefox. All other sites are fine. Wait and hope for the best

Firefox fixed the bug. now i can use the site again. took some days, but now is ok.
