I'm changing the title to distinguish this from bug 1698140 (this is for PDF attachments that should be opened internally in Thunderbird, and the other bug is for PDF attachments being treated as a HTML when they are opened externally).
This title change is a bit verbose, but I couldn't think of a better one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945741 Title: [upstream] PDF attachment opens in Firefox instead of the built-in viewer when opened from the compose window To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1945741/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
