I have used Thunderbird with an add-on that enabled the use of recorded voice announcements identifying incoming messages so that I did not have to come back upstairs to the computer to determine what it was. The upgrade to Fedora-30 requires the use of a Thunderbird version that no longer supports the add-on [Tonequilla]. Until now I dnf downgraded Thunderbird and then the add-on could be installed, now downgrade gets Thunderbird 60.6.1 (64-bit) for which the add-on is disabled and not available.
I unpacked the xpi file, changed the install.rdf to allow Thunderbird 60.*, repacked it, and installed it. No errors and the play sound option is in the filters. I didn't actually test it though. Worth a try.
