Rated 5 out of 5 stars

I have been using this add-in for some time now and it works really well, thanks to the developer! One quick observation/bug though, on Firefox Mac version it creates a .part file in the download folder and I have to manually remove it, something like ffCPJ1Ad.zip.part. It doesn't happen on Windows.

This review is for a previous version of the add-on (4.0.1). 

Thanks for the bug report - I can't really test it though, I don't have access to an OSX machine within a foreseeable future. Sorry! -- Maybe you could try to set a different "download path", somewhere inside your user folder? I presume the access rights just don't fit.
