There is a bug on Thunderbird mail to 91.1.0. The default for mp3 is set on VLC media player. When I try to play a voice mail (mp3 format), you get a pop up message.
“What should Thunderbird do with this file?”
You get the pop up box every time you try to play a voice mail, even after you check the box to “Do this automatically for files like this from now on. Should I report this as a Thunderbird or KDE bug?
Looks like I’m on version 91 now! Interesting, since this is a recent Manjaro installation, yet forcing the mirrors to refresh was needed for the Thunderbird update to show up.
@fhins I tried again with Thunderbird 91, and renaming / deleting handlers.json does in fact reset the the “Open With” settings to the defaults. You can try to reconfigure it from that point forwards, in case there was an errant setting in the handlers.json file.
