1 month ago @philg-dev I face the exact problem although I don't use Master password.
I added StartupWMClass=Mail to my thunderbird.desktop but it didn't help:
cat /usr/local/share/applications/thunderbird.desktop[Desktop Entry]
Encoding=UTF-8
Name=Thunderbird Mail
Comment=Send and receive mail with Thunderbird
GenericName=Mail Client
Keywords=Email;E-mail;Newsgroup;Feed;RSS;Calendar;Contact
Exec=/mnt/Data/opt/bin/thunderbird %u
Terminal=false

I've installed Thunderbird with the instructions on the mozilla KB.
The
Thunderbird.desktopfrom this repository, which is part of the instructions, has a small, but annoying issue with the GNOME Dock: When you add Thunderbird to your favorite applications it gets pinned to the Dock. That's especially useful, when you want to use simple shortcuts to switch between your favorite apps in a consistent manner (e.g.<Super> + 1~9to access the applications in the Dock).However with the given
Thunderbird.desktopfile, when I open Thunderbird and I confirm my master password prompt, the Thunderbird main window will open with a separate icon in the Dock (window title "thunderbird-esr"), whereas the pinned desktop icon is properly titled "Thunderbird Mail".The problem is, that I switch focus to my open Thunderbird with
<Super> + 2anymore in that case because the pinned desktop icon appears "inactive", since the main window is in a different spot instead. So that breaks my usual workflow a lot.Solution
I was digging deeper on the problem and I could solve the issue by adding the following property to the
Thunderbird.desktopfile:(Edited after the discussion below. Before the discussion my solution was
StartupWMClass=Mail, but it turned out that only works on X11, but not on Wayland.)Resources / Approach
To get to this solution, I inspected the X-Window properties of both the master password prompt and the Thunderbird main window with the
xpropcommand.The Thunderbird master password prompt always has:
WM_CLASS = "Thunderbird", "thunderbird-esr"The Thunderbird main window always has:
WM_CLASS = "Mail", "thunderbird-esr"Maybe somebody who is more knowledgeable on this topic could enlighten us why and how my solution works. I only know that it works for me and I have a general suspicion on how it works.
I came across a similar issue that has been fixed for VS Code to get to this solution.
Assumption on how it the problem and solution works
Thunderbird.desktopiconWM_CLASS=Thunderbirdget's associated with the desktop icon, since there's no explicitWM_CLASSspecified in theThunderbird.desktopfileWM_CLASS=MailWM_CLASS=Thunderbird, the main window gets a separate icon in the dock because theWM_CLASS=Maildoesn't match with the one associated with the pinned icon.WM_CLASS=Thunderbirddoesn't match the now explicitly definedStartupWMClass=Mailfrom the fixedThunderbird.desktopfileIf anybody can confirm my theory or suggest a more solid solution, we could make a pull request in order to get the fix out to everybody.
