Bjr, la barre de tâche verticale à gauche, avec des icônes n'existe plus dans Thunderbird installé sous Windows 11. Bizarre. J'ai désinstallé, réinstallé, j'ai essayé de la faire réapparaître en passant pas le menu Affichage. Je ne trouve pas. SI vous avez une solution merci

Hi Pascal,

If you could attach a screenshot, then it would be easier to diagnose the exact issue. What does this "sidebar" contain?

Regards, Balázs

Thank you. I actually can't take a screenshot because that happens on a friend's laptop PC who is now far away. I tried to help through a Teamviewer session. When you launch Thunderbird, on the left side, there's a vertical toolbar with a few icons, for emails, contacts, calendar, settings (I wrote taskbar by mistake). That toolbar has disappeared. I think it's maybe possible to solve the problem by reinstalling an old version and after an automatic update the taskbar will maybe remain. I will try this and will tell you if it worked.

Thank you, that's exactly what I needed. That's the Spaces Toolbar, you can turn it back on using View -> Toolbars -> Spaces Toolbar. If you don't have the menu enabled, press Alt+V to open the View menu. Or you can also use the main menu (hamburger menu).

Thank you Balazs, I transmit your advice. I'll tell you if it worked.
