Having upgraded to Thundrbird 60 (portable version) the menu and title bars seem to have become amalgamated so that the chat and hamburger icons are overlaid on the windows control buttons (minimise, maximise, and close) so cannot be clicked or moved in customise mode as the windows control buttons take priority.

Chosen solution

Suggestion from a developer....

Do you have a userChrome.css file in the profile that might affect this?

If not try to renaming xulstore.json in profile with closed TB. This resets the whole appearance.

Thank you for testing safe mode. That's a strong indication that an installed theme, extension or some other customization is causing the issue. Can you research those items?

I only have two extensions, Lightning and provider for google calendar, no other addons, extensions, or themes.

No userChrome.css file in the profile but renanaming the xulstore.json file with Thunderbird closed reset everything so I now no longer have the chat and hamburger menus overlaid on top of the windows buttons.
