Since my last post died and I discovered soem new issues, I'll just open a new discussion:

All Issues I have:

1. Hidden Posts can't be opened. I click on them and nothing happens.
2. When i click on an item, Tf2Outpost opens a new tab displaying the information there instead of a overlay.
3. When I click on "add a new trade" or the search function, Outpost won't load the the general item list nor the my backpack.
Everything works fine when I click on the Backpack option in the toolbar or on profiles.

I'm using Windows 7 and Firefox. I already tried to disabele every plugin, Firewall and Anti-Virus programs, but that didn't work either.
