Hello there We have read the message We try to help

The inbox or program stays blank? Or the complete program stays blank I can offer you a complete workaround .

Can you go to the inbox? What version and pc is been used for this at the moment please?

Greetings Firefox volunteer

I cannot get to the inbox.

System: Mac OSX Sequoia Version 15.4.

I don't think I fully answered your question. The whole program screen is blank. None of the toolbar itens across the top responde.

Thank you for any help you can provide.

Tool bar: I mean, the items expand, but then nothing happens when selecting from the drop down list.

Thanks for the link! The information was exactly what I needed. Everything is back!

After upgrading to the latest MacOS, my Thunderbird interface is blank.

Use the keyboard shortcut ⌘ + 1 to switch to the Mail-tab. If this doesn't work launch Thunderbird in Troubleshoot Mode: hold the Alt(Option) key and start Thunderbird....
