Thunderbird Support Forum

Hi all,

I recently updated, and am now on the following version: 115.0.1 (64-bit) Mozilla Thunderbird Flatpak en-USthunderbird-flatpak - 1.0

After the upgrade, if I click a mailto:// link, the system sits still for a bit, then comes up with a dialog that says:

"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."

Now, I've researched this and I've deleted the lock and .parentlock files. That did not resolve it. I also found a fix where i moved the Mail and ImapMail folders out, which are then rebuilt. But that also did not resolve it.

Currently I'm without a major part of my workflow.

Does anyone have any suggestions?

Thanks so much
