Problem with duplicate icons in Linux Mint 22 Cinnamon, Mate, Xfce in the taskbar solved by me

[Anonymous]

When Thunderbird is pinned, duplicate icons appeared in the taskbar on Linux Mint 22 Cinnamon,

Mate, Xfce. I have adjusted the starter.

The problem was posted in the Linux Mint forum under Software and in the German forum, but reached too few users. Please change this so that all Thunderbird users no longer experience this cosmetic error.

heres the code

Code: find

Exec=thunderbird %u

add the line

Code:

StartupWMClass=thunderbird-esr

Save the file
