I am also experiencing this. Hopefully this will be fixed soon.

Edit: Instead of scrolling to the side make it so that the window width an be adjusted to make it wider.

I also have this problem as well as several other steam users: http://steamcommunity.com/app/427520/di ... 202058287/
Please resolve this issue so the mod portal can be accessed.

I have the same problem. I just created a forum.factorio.com account, a factorio.com account and a account on factoriomods.com but I get the same error and still 'your account is linked with your steam profile'
