I tried to download latest version multiple times but it didn't help. I have firefox 9.0.1 and when I click: Help -> about firefox there's written that it's up to date. I came across a problem also while posting a message on one of forums: Gamedev.net. I couldn't check the message window in order to type anything. Hwo can I solve these problems?
