I have no idea whether some of the old, old comments in this bug report are still relevant or not, but there was no mailto problem between Firefox and Thunderbird in Fedora 29, or any earlier Fedora release in recent years that I can recall. I first saw this symptom in Fedora 31, which currently has Firefox 75.0 (64-bit) and Thunderbird 68.7 (64-bit). It does not occur when Chrome is the browser and Thunderbird the default email client.
It is unclear whether the recent visibility of this symlptom is caused by underlying changes in Fedora 31, Thunderbird, or Firefox, but since the error only occurs when both Firefox and Thunderbird are involved, that points the finger at one or both of those applications. From the users viewpoint, these are two independent applications. Whatever status information or internal support that Firefox and Thunderbird are sharing that causes this problem, they obviously shouldn't be sharing. It should be irrelevant to Firefox's external behavior whether Thunderbird is the default email client, and irrelevant to Thunderbird external behavior whether it receives a mailto request from Firefox or some other browser. This defect is a major annoyance, as I frequently use web sites with mailto links, and Firefox and Thunderbird are my preferred applications for browsing and email. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/711305 Title: Thunderbird is already running, but is not responding.
