Sebastian, It seems like you are correct and this depends on configuration.
I've received a reply from Mozilla about my bug: ... According to the previous stack trace, it's not a Firefox bug neither a Flash one, but a FFDShow one. You are using version 1.1.3761.0 while the current one is 1.3.4500. Update FFDShow: http://ffdshow-tryout.sourceforge.net/download.php Then report back. ... You can track this here: https://bugzilla.mozilla.org/show_bug.cgi?id=850614 Will try their suggestion and inform you about the result. Best regards, Irina.
