Anything in Tools -> Error console ?

Nothing in Error console. It's like if labels are missing in menus.

Antoine are you using the default theme ?

(In reply to comment #4) > Antoine are you using the default theme ? yes, default theme.

With Lightning extension disabled, menus appear. With Lightning enabled, menus are invisible. So I think the problem is coming from the extension.

Antoine, are you using any other extensions besides Lightning? If yes, can you disable them one by one to see if the problem persists?

I see this error happen with only two extensions installed in TB 3.0: lightning 1.0beta1 rc and quickfolders 1.6 When I disable the quickfolders extension the menu entries appear correctly.
