Kubuntu 22.04, snapd version 2.56.
When running the latest stable snap (102.0.1) of Thunderbird and trying to send a URL link via email from the Firefox snap (102.0) using the “Email a link to this page” button from the Firefox toolbar, I get the following popup dialogue box:
“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”
If the Thunderbird snap is not running, I get an email compose window from the Thunderbird snap as I would expect.
I have tried the various web instructions of removing the .parentlock when Thunderbird is not running, but that is re-created when Thunderbird is launched.
Is this a Thunderbird snap problem, or a Firefox snap problem and where is the best place to report it? I have searched the Firefox Bugzilla site and found nothing which matches.
Thanks in advance.
