I use last version of AjaxUploader with HTTPS

It works fine with IE. But I get this error message in Mozilla Firefox after file upload "Unable to find the uploaded file in directory pathtotmpdir". I not see file in tmp dir during uploading via Firefox (I see it during upload in IE). Where do it store files? I have no this troubles in my test environment with Firefox which uses HTTP (not HTTPS). Live site uses HTTPS only.

 

I read this http://cutesoft.net/forums/thread/48311.aspx, but I can't undestant how to use uploader.FlashUploadPage and what this page must do.

 

Please advice.
