I hope there is a simple solution to this. This is a Mac Monterey system. Right now I am using Firefox. About three years ago I gave my State's Court system access to my Comcast email address, which syncs with Thunderbird. About two days ago I found, before I saved previously one of the attached documents, that the PDF Court initiated attachments no longer opened. I have not dismissed some kind of administrative mischief at their end on the part of some IT professional they employ. Instead of opening the document, they instead open a tab showing the message thread to which they attached the original PDF. Since these are Court documents, and their is personal injury involved, of course they are important to me. So, I am interested in recovering these documents. Does my Thunderbird, which I constantly check for updates as I do Firefox and this whole Mac Monterey system, need some kind of repair? Unfortunately, since I have a Windows 10 with Thunderbird (Microsoft no longer supporting its original Mail program), these messages do not appear in that installment of Thunderbird. These messages go back to 2022; and on the Windows 10, the oldest messages only go back to 2023. Again, I hope somebody knows a simple fix. I had A+ training from DeVry; but XP was the going OS then. Thanks in advance for anyone who has possible solutions. Have a good day, otherwise, hopefully better than mine.
