Did you check the settings in Tools > Options > Applications ?

See "Reset Download Actions": http://kb.mozillazine.org/File_types_and_download_actions

Hi All, i have checked the Tools > Options > Applications, but i didn't see "Reset Download Actions". I solved this problem by installing Flash Player. Now i can play swf in firefox.
