Browser Support • Layout Of Top Of Screen Is Wrong

The text to the right of the "Pale Moon" button isn't supposed to be there. To the right of the "Pale Moon" button should be the tabs. This just happened. I've played with various possibilities and looked at Preferences but can't fix it. I downloaded the current Pale Moon version yesterday but didn't see the problem then. I reverted to the previous version, but that didn't fix it. What happened?

EDIT: Also, the icon between the Bookmarks button and the D/L button isn't supposed to be there.
