Since the main upgrade, I guess around version 64 or 69, thunderbird become much less user friendly, there are tons of difficulties that before there simpli weren't. For example I can't save to desktop an attachment by simply drag and drop from email, I need to chose "save object to".. horrible. Difficulties to see the author name and copy it, etc. Before it was much more quick and friendly.
Now I have a new problem, I've received a receipt with QR code, I can't print it, the print function is grayed out, why? I can't zoom the message out to do a screenshot, I have no instruments to save it as a picture and send it. I really hope you may focus in all these problems instead of new features. Thank you
