On Linux Mint 18.3, with whichever KDE is current in their repos.

After the recent Thunderbird update to v. 60, FireTray Extension no longer worked, so I changed to "MinimizeToTray Reanimated" & it doesn't provide a 'Start Minimized In Tray' option the previous FireTray did.

So in my infinite wisdom, I set the KDE Special Window/Application settings [0],[1] to 'Apply Initially' > 'Minimized' for the Thunderbird application. Problem with that now is no matter what I do the window won't appear. Stays in the tray when it should restore.

I didn't see anywhere that these type of settings are available to edit via 'System Settings', but I imagine there's a text file I can edit somewhere- just don't know where to look.

Help is appreciated. Thanks in advance.

Solved by starting Thunderbird in safe mode without any addons enabled:

Code: Select all

thunderbird -safe-mode


Then I was able to disable the problematic "Special Window/Application Settings" from the titlebar's context menu.

Exited & restarted & now all is well.

...Still won't start in the tray, but better than not being able to see the window at all.
