Upgraded Thunderbird from v78 to v91. The Message pane is white with black text (as it was before upgrade). The sidebar with the accounts and folder hierarchy is black with black text. How do I get sidebar back to white with black text?

Thank you.

Well, sorry, never mind. I was using a custom theme. Works OK with TB ver 78, but not with ver 91. Went back to the default TB Light mode.
