Hello, when I click on an e-mail attachment, a windows always pops-up that asks me what to do. I have "Do this automatically for files like this from now on" checked but the pop-up appears every time. If I select "Save file" than next time the dialog window for saving pops-up automatically. Only PDF files are opened without asking. The error started immediatelly after updating to Thunderbird 91. In compose message window a double click on the attached file works fine. I tried to delete the associations in preference and create them new but with the same result. As I open a lot of attachments, this bug is really annoying me. How can I resolve it?
