Not a bug on the website, that's what the theme looks like. There may be a bug in your installation of Thunderbird, perhaps you have a conflicting add-on, theme, or some other setting. Or it's not enabled properly. I don't know. You can find support at https://support.mozilla.org/en-US/questions/new/thunderbird

This is what the theme looks like when it's installed and working correctly in Thunderbird 78.2.2:

The error occurs when I upload the XPI file and your system automatically generates a thumbnail, this thumbnail this is worng, my theme n(d).white.fresh, as the name implies, it is cool white and does not include any dark or black sectors The error does not appear in the installation of the theme and the capture that you show me is correct

Your first screenshot didn't show the icon so I thought that was what you were reporting. You're correct the preview is somewhat wrong,

I suspect this is due to the newer property names and we don't have the patch that fixes the preview generator for those yet. Will eventually fix.

Thank you.

Likely patches here: https://github.com/mozilla/addons-server/commits/master/src/olympia/versions/tasks.py that will fix this that need backporting.
