And all site Poster hangs?

After viewing any trailer (for example, www.afisha.ru/trailer/1683 ) and trying to go to any other page, the browser hangs.

Firefox 2.0.0.14
Adobe Flash Player version 9.0.124.0
Windows xp

This happens both on the work computer and at home. All Firefox add-ons disconnected - the result is also the same.
