I use a portal for work and am required to download a variety of documents for specific tasks. When I download certain documents, predominantly Word documents, they are saved with a file name that ends with the word attachment, e.g. 'abcd.docx,attachment'

This does not happen with any other browsers that I use and I know the obvious answer is to use those but I'm interested as to whether anybody else has had this problem and whether they have found a solution?
