Safari doesn't download files, it instead tries to open the url associated with the file.

As stated in the title, when I try to download a file from the internet, clicking on the link associated to the file will not start a download, but instead opens a new tab in my browser showing the url of the associated file. If I then right-click and choose 'Download linked file as...' the file can be downloaded with no issues in most of the cases, at least as long as the website allows right-click downloads to happen.

Does anybody know why this could be? I have tried resetting Safari, emptying the cache and, of course, updating my software. It is a midly annoying problem, but it doesn't happen when I use other web browsers in my iMac. Any help would be appreciated. I'm using Lion in a late 2009 iMac with, as I said, updated software.

Thanks!
