Hi all, since the last firefox update I am not able to visit the german Amazon Seller Central website anymore. I have no knowlegde in how to solve this issue and that is why I am asking for your support. The link to the website is: https://sellercentral.amazon.de/ Whenever I want to visit the site, I get the error "HTTP Status 400 – Bad Request" (see attached image). I already checked with amazon themselves, but they said the issue lies within my computer. My IT department said the issue is related to the browser most likely; and indeed, with Microsoft Edge for example, I am able to open the website. Does anyone know this error and even better knows how to solve the problem? Thanks in advance!
