Firefox incorrectly reports "Thunderbird is already running..." error with "Email Link"
Revisions: Firefox: 72.0.2 Thunderbird: 68.4.1 Linux distro/release: Fedora 31
When trying to email a link from Firefox (File->Email Link...), it eventually returns with an alert saying "Thunderbird is already running, but is not responding. To open a new window, you must first close the existing Thunderbird process, or restart your system." I have never had this problem before, so:
1) I shut down Thunderbird, and tried "Email Link...". That worked. 2) I restarted Thunderbird, and tried again. Same problem. 3) I captured the command line Firefox uses to send the email message text to Thunderbird using "ps -ef | grep thunderbird", and ran it manually. I was able to get a normal email editing dialog with the appropriate text filled out:
[rlm@localhost Local Folders]$ ps -efw | grep thunderbird rlm 119199 1939 36 05:57 ? 00:00:21 /usr/lib64/thunderbird/thunderbird rlm 119453 1764 9 05:58 ? 00:00:00 /usr/lib64/thunderbird/thunderbird mailto:?body=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DOHTSxw6zN1E&subject=(1)%20The%20Shins%20-%20Australia%20%5BOFFICIAL%20VIDEO%5D%20-%20YouTube rlm 119460 119453 1 05:58 ? 00:00:00 [thunderbird] <defunct> rlm 119468 9686 0 05:58 pts/0 00:00:00 grep --color=auto thunderbird [rlm@localhost Local Folders]$ /usr/lib64/thunderbird/thunderbird mailto:?body=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DOHTSxw6zN1E&subject=(1)%20The%20Shins%20-%20Australia%20%5BOFFICIAL%20VIDEO%5D%20-%20YouTube
How is Firefox concluding that Thunderbird won't let it run properly?
