Disable opening an about:blank Window on opening an PDF attachment when Browser is set to open PDF Files with an external Program
Disable the "Feature" as it is named by your Support Team and Developers. (Support Ticket GFI-180220-628136)
We've set up our Browser to open PDFs externaly, not with the PDF Viewer of the Browser because of company policy.
Every time you click on an PDF attachment, a second about:blank browser window is opened, which has to be clicked away by the user.
The "Feature" isn't occuring when the user chooses "Save as" instead of open, so it shouldn't be much of a hassle to implement it as well for the option to "Open" an attachment.
