[tde-users] Still having issues with Firefox and Thunderbird on TDE

Unfortunately, I am still having issues with Thunderbird and Firefox, where Thunderbird creates Blogs & News Feeds, instead of sending a link for Firefox to open. But if Thunderbird mysteriously behaves as expected and it sends the link to Firefox to open, Firefox will then display it's not the default web browser, yet running a command to check the default browser, shows it's Firefox. I have attached a screengrab of the two windows. Is there any harm in uninstalling Konqueror from TDE and using something else as a file manager? The only other solution I see, would be to uninstall both Firefox and Thunderbird and use Vivaldi and it's mail client (after it's turned on) and use that from now on.
