Thunderbird is already running, but not responding. To use Thunderbird, you must first close the existing process, restart your device, ore use a different profile.
I'm running for quite a time Thunderbird on Windows up to Win11 without any problem. For about 3 years I'm using the same TB profile in dual boot environment with Linux Mint (v21 until last week and now version 22). I understood why I didn't get access from Linux side after the latest TB update in Windows as obviously the file structure and other things had changed to make it incompatible to elder versions.
However, as Linux is now my normal working environment, I've tried it again after upgraded my system to Linux Mint 22 Cinnamon 6.2.9 , kernel 6.8.0-44-generic and failed again, having the same error message when starting the profile: "Thunderbird is already running, but not responding. To use Thunderbird, you must first close the existing process, restart your device, ore use a different profile. "sudo killall Thunderbird" didn't find a running process.
I've tried importing everything in a new profile, which worked (more or less), but failed with all attempts getting access to my local profile. A local profile appears after importing but contains no data, trying to import its data separately doesn't trigger any error message when just ticking "E-Mail", but nothing is imported. When ticking "E-Mail" and "Settings", I'm getting a red alert that asks me to look into the error console which doesn't help either.
What can I do ????

Huh, I forgot to write that I even copied the mentioned local profile into my .thunderbird environment without avail, and into my home folder with same results. And I didn't mention that I found the same questions even here: https://support.mozilla.org/en-US/questions/1440794
However, the chosen solution seems to be rather frustration tha a real solution. I've tried it and also killing .parentlock and lock (the latter marked as wrong link in the file system) didn't work.
I fact, I have my mail archives stored in my local folder. It's a pain in the back always being forced to change to windows before mailing or storing anything outside IMAP folders. Actually, it's the first time I'm really happy still having Windows as a working backing system.
Mint is part of the problem. It uses ubuntu as a base and they now use sandboxed snap packaged instead of the older package manager format. ARCH I think.https://ubuntu.com/core/docs/security-and-sandboxing
The already running can be caused by the presence of a parent.lock file in the profile. With Thunderbird closed just delete the file.
Hi Matt,
Thanks for your proposal, but deleting "parent.lock" doesn't work. That's what I've found already in some fora. Before I've deleted even more, e.g. "lock" (a link, marked "faulty" in Linux) and ".parentlock" (0 byte).
Linux Mint 22 doesn't use Snap per default (I think it's installable - I'm not sure). Even more, they have introduced a purely Debian based edition - because of Canonical's own development paths - like Snap. Nonetheless, even being an apt package it might be broken somehow as it seems that the Mint guys are quite involved in some parallel developments concerning their code basis. However, I'll try asking in the Mint environment as well.
Before the last major upgrade of TB I'd been able to access both profiles from Windows and Mint. Both are stored outside the normal Windows environment, on a different drive. Instead of further trying to get access from Linux side, I created a pretty new profile and was able to import almost everything but my local folder.
I'm neither a dev, nor a Linux nerd. Rather a power user and I'm teaching on a voluntary base how to use TB and other useful FOS applications. As far as I can see the local content wasn't touched by the upgrade and is still in the original text format as it was before. It still works fine under Windows. I've even tried to copy it into the ".thunderbird"-folder in Mint, but it doesn't change anything. Linking the path even to this internal location still shows nothing in TB (as before) and the import fails as well.
I have exactly the same issue under two installations of Fedora 40. But I use Cinnamon so it might be the common factor (I have only RPMs on both systems, no flatpak or the same). Interestingly enough, the following works as expected:
xdg-email myname@example.com thunderbird mailto:myname@example.com gio open mailto:myname@example.com
It gets even weirder: while clicking on a mail link in firefox, I see that it ultimately calls
/usr/lib64/thunderbird/thunderbird mailto:myname@example.com
If I call the same from the command line, it works and doesn't get stuck.
One more piece of information: clicking on a mailto link in LibreOffice, or sending a file via email, works as it should, so it might have something to do with the way Firefox tries to send e-mails via Thunderbird. This said, I created a small script to know how it's called on mails, and it's simply called with `mailto:myname@example.com` as parameter, nothing else.
I think, I found a workaround and posted it there: https://bugzilla.mozilla.org/show_bug.cgi?id=630548
tl;dr: the MOZ* environment variables set by Firefox while calling Thunderbird do cause the issue.
Hi Eric, obviously several people do have the same message. At a first glance I didn't see any Win/Linux dual use of the same profile. I read somewhere that this kind of profile sharing never had been intended, even if it worked before without any issue. I think as well that it is a real bug. I wasn't able testing the way as you did as TB was not responding without any active local profile. I managed before the connection via the profile Manager and manually connecting the existing profile on a NTFS drive, making it, when working as expected as before, the default starting one. When choosing this profile now, I'm still getting the error message. EDIT: It stuck before I'm asked for my main password.
Well, now I doubled all local IMAP data (several different mail accounts), by having now an own profile in both worlds. Nonetheless, somehow I saw the miracle that the local profile, my mail-archive, is now accessible again from both sides and the calendar is synchronized via my NAS anyway.
However, thanks for sharing your ideas.

I'm using Thunderbird 128.3.1 (installed via flatpack) on Linux Mint 22. My problem is that if I exit Thunderbird and then try to run it again I run into the "Thunderbird is already running ..." error, even after a restart. The issue seems to be the ~/.thunderbird/lock file. When I delete this I can (re)start Thunderbird. The file is listed as type link (broken) and appears to point to 127.0.1.1:2. While it works to delete the file each time I want to use Thunderbird this is clearly tedious. Where should the link file point, or is there another way of addressing the problem?
I have Thunderbird 128.4.0esr, Firefox 132.0, under Fedora 40.
This CONTINUES to be a problem, and the suggestion of "close the application and then click on your link" is just completely STUPID. It's on a Microsoft level of stupid. This a BASIC function of a browser, email client, etc. The thing is, Betterbird can handle this with NO problem, so I know it must be a bug in Thunderbird.
Seems like the Mozilla organization is spending way, WAY too much time on pursuits that bear absolutely no relevance to software quality.
I think I made the mistake of not becoming Amish (well, not Amish, but maybe retreating to some remote Shinto shrine I could spend my days restoring).
