Thunderbird 78.5.1 on macos 10.15.7 won't start after recent update

more options

I recently updated Thunderbird today and although it restarted fine after hitting the "restart to install" (or similar button) in the "about" popup on osx 10.15.7 (latest Catalina version). After I restarted the computer, Thunderbird no longer starts up properly - no error message, nothing.

I even tried to invoke at the commandline in normal and safe mode and the response is "Killed: 9" :

$ /Applications/Thunderbird.app/Contents/MacOS/thunderbird-bin Killed: 9

$ /Applications/Thunderbird.app/Contents/MacOS/thunderbird-bin -safe-mode Killed: 9

I've tried removing the .parentlock file from the profile directory located at ~/Library/Thunderbird/Profiles/[default profile name].default/.parentlock but it doesn't help, just gives same "Killed: 9" message at the command prompt.

Please help, I need to access my email.

Thunderbird 78.5.1 20201130232704 20201130232704

Thanks.

Chosen solution

OK, I got it working. But only *after* I completely un-installed Thunderbird by right-clicking on it in the Applications folder, selecting "Move to Trash", downloading the latest OSX-specific .dmg application bundle from the thunderbird.net website (with no apparent SHA sum or MD5 sum, which means, how do we as consumers know if this is a legit binary or not?), and re-installing at which point the familiar OSX popup occurs, asking if I want to open the Thunderbird app downloaded from the internet, to which I click the Open button and now, Thunderbird is working for me once again (verified after a couple of reboots).

This still looks like a serious bug to me and whoever is responsible for developing/porting to OSX needs to look into this. I might file a bugzilla bug if I have time.

The only thing I can think of is that my VPN client connection may have gone down after the update at which point I connected to a different VPN server so maybe something internal to Thunderbird got in some weird state? Not sure but I've since rebooted several times and still have the same behavior "Killed: 9."

I've tried looking for any log files but I have no idea where any Thunderbird logs are kept. I see a folder called ~/Library/Thunderbird/Crash\ Reports that contains several ASCII files named "InstallTime[Apparent time stamp format] but even when I examine the most recent one that was created today on or around the time I performed the update to 78.5.1, it contains no crash data (to my eyes), just some 10-digit number.

I'm puzzled. Please help.

Thanks.

OK, after digging a little more I found some crash info at the system level by invoking the /Applications/Utilities/Console program in osx, look at the Crash Reports tab and I do see crashes for every time I have tried to unsuccessfully launch Thunderbird after the update to 78.5.1. They all have similar forms:

Not sure what's going on but maybe a problem with OSX Code Signature / Code Signing?

I got the same problem since the update this morning. I am on the MacOS 11.0.1 (latest BigSur version).

Not sure how we as users can solve this. Looks like developers need to tell us how (if even possible) to work around this?

Hello, any developers out there?

In my case Thunderbird started working again after some time. I did nothing so I don't know what the problem solved.
