Can't use my webmail (Vivaldi macOS issue)

Hi!
I just can't use my Webmail because of a kind of form that need to be fulfilled but is inactive. See the screen capture: https://youtu.be/AdszFzheTlY

@voicemorpher No problems here signing up for a test account and filling in the webmail account form.

Please try the troubleshooting steps first:

@pathduck thanks! Got it. Webmail initial form conflicts with this Lingvanex extension: https://chrome.google.com/webstore/detail/lingvanex-translator-and/kdamfjkjgaidaigdfelkpgdnbigclccc?authuser=3
