On my Mac I have always selected attachments in Thunderbird emails and dragged them to copy to whatever folder I select on my desktop or our server. That suddenly quit working around September 22, 2025. I tried updating to the latest Mac system (Tahoe 26.0) but that didn't help. Thunderbird is also up to date (143.0.1). I get no message when I try dragging, it's just that nothing happens. I have tried disabling add-ons, starting in Safe Mode, reinstalling, etc. I have no trouble saving from the attachment "Save All" but I prefer the efficiency of d/d. I also have no issues d/d from my desktop into an email or d/d inline images out of an email. I just can no longer d/d attachments. Any suggestions?
