Thunderbird Menu Bar Icon Missing

relaxandreflect wrote:

Mozilla Thunderbird provides a Menu Bar icon in the upper right as a badge that shows unread messages. I accidentally removed this button by dragging it off the bar, and cannot get it back.

I tried uninstalling (deleting Thunderbird preferences files) & reinstalling, but it will not show in the toolbar and does not show in System Settings>MenuBar>Allow in the Menu Bar (it showed there before it was removed).

I also tried deleting apple.systemuiserver.plist and rebooting, but no luck.

I am on a Macbook Air M4 with Tahoe 26.0.1. Any help is greatly appreciated.

for your third party —if in doubt search the developers website or contact their: Support/Help/FAQ/Known issues/compatibility/updates…

see if this is it(?)

Thunderbird, go to View > Toolbars in the main menu, and then select Customize Toolbar to drag and drop items you want to add or remove.

Try looking into the configuration options within the Thunderbolt app itself.
