Can't type my password, new tab open on browser to signup page

[-Araman-]

I was normally playing, got disconnected and sent to login screen, when i tryed to click in the password field, my browser opened https://warframe.com/signup.

Every place i click on the login screen, i got a new tab on my browser to the same page.

I usually play in borderless fullscreen, tested in fullscreen and windowed and happened the same. Tryed to run the game as administrator, didn't work aswell. I can type my password if i click several times in the field and can login, but even doing fast, it still opens a new tab.

Sorry for any language mistakes, English is not my primary.
