I don't know how this might help, but I followed the instructions to download and un-squash the version 102.0.1 of thunderbird to my home folder, cd'd into the squashfs-root folder and ran thunderbird using ./thunderbird -p which picked up my current profile from the ~/.thunderbird directory. >From another terminal window and within the same squashfs-root directory, I >can successfully run ./thunderbird --compose which then brings up a compose >window whilst thunderbird itself is still running.
Make sure that you make a backup of the ~/.thunderbird folder first, running the latest version of thunderbird alters the profile. Does this add further info to the problem? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1980839 Title: thunderbird -compose returns error since the 102 snap update? Status in thunderbird package in Ubuntu: New Bug description: After updating to the latest thunderbird 102.0.1 snap on Ubuntu 20.04, it is no longer possible to open mailto links from the firefox snap in thunderbird. When clicking a mailto link in the firefox 102.0.1 snap, thunderbird returns the following error message: "Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile." The issue appears related to the thunderbird update as there was no issue opening links in the previous 91 version.
