Hello - I have 4 users so far reporting that in Outlook in Office365 the download hyperlink stops working. When you hover over it, the arrow cursor doesn't change to the pointing finger, nor does the link turn blue like it's active. The "Save to One-Drive" link right next to it works fine. The same email accounts work fine in both Chrome and IE/Edge. They are all using the 58.0.1 version of Firefox, and I have tried dumping their cache, restarting without add-ins and refreshing Firefox with no results. Any help would be appreciated.

Thanks.
