Rated 4 out of 5 stars

I really love this extension - but since FF3 I've got problems with uploading jpg or swf files - the files on may webserver cannot be used: jpg's are shown, but the image is destroyed, swf's can't be played.
is this a known bug? can anybody tell me why this happens?

This review is for a previous version of the add-on (0.99.1). 

You might be in ASCII mode - try going to Tools->Options->Downloads/Uploads and selecting Binary mode
