In Thunderbird 107.7.1 on my MacBook Pro with M1 chip - When attaching a pdf to an email getting ready to be sent I am not able to open it and check if the pdf file is in good shape. I use Adobe Acrobat Pro as my preferred pdf reader and this is associated in control panel. I always check pdf's prior to sending to make sure it is correct. As soon as I click on the pdf attachment in the ready to send email I get the following "File name - Cannot be opened because an unknown error occurred. Try saving to disk first and then opening the file." However, I am able to open pdf's with Acrobat Pro that are attached to emails that I receive without a problem. I have used Thunderbird for many years and this needs to be solved so I can do my business properly. Please advise as to how to get this corrected. Thank you. Bud
