Created attachment 17113 [details] The file with the problem, downloaded from http://www.spreadfirefox.com/en-US/worldrecord It seems that swfdec-mozilla doesn't load all necessary files to load the application. Apparently ammap.swf requires other files hosted in that server: ammap_key.txt, ammap_data.xml, world.swf and maybe others, but it seems swfdec-mozilla is unable to determinate their location and load them. I can't determinate if there are also others underlying bugs.
This is working fine here with latest git.
