Print Preview when printing Gmail attachments?
When clicking the print button in the interface of Gmail, it opens the attachment in a new tab and shows the system print dialog. When closing that dialog, the tab is closed too.
As a consequence, it doesn't seem to be possible to print attachments from Gmail AND view the print preview. I had some cases, where a previous "scale" setting led to attached scans being printed at half the size of the paper instead of full size, with no noticeable prior warning; By comparison in Chrome the print preview would have shown the issue in time.
Is it somehow possible in Firefox to obtain similar behavior?
A related question is https://support.mozilla.org/en-US/questions/1215520, but it doesn't apply here, since I need the preview to be shown, when the webapp at hand initiates printing.
