Trouble signing in with the code

[Leostereo]

Recently I deleted all my browser information, cache, passwords, anything really. So therefor I needed to sign in to all websites again. I am a very active trader (in TF2), so I use websites like TF2TP and TF2Outpost, and they require me to sign in through steam on their website so that my backpack can be linked. When I try to do that Steam says that I'll have to enter a code since it's either a new browser, computer or similar. So I get the code from my mail and enter it, but then it just stops loading, nothing happens no matter how long I wait. I'm on a mac (I have a PC too, as desktop, Mac haters!), if that would matter.

tl;dr - It doesn't load when I enter the code when signing in through steam on several websites.

Help, anyone?

Edit: And I've tried using both Chrome and Safari. It also worked perfectly fine before. It's been like this for over a week, I've tried to log in almost every day.

Maybe re install the browser ? Are you using a mac or windows ?
