I accidentally messed up something with the mouse and now part of the edit bar disappeared
If View > Tool bar is ticked then the tool bar should be there somewhere - it could be detached from the main window but will always stay on top.
Once you have found the bar, press on the blank strip right next to the save-disk-symbol and drag the bar back to the desired position. THere release the mouse button.
For your search: it is possible to move the tool bar to the very edge of the desktop but a little bit of the frame will still be visible. You can grab that piece of frame to move the tool bar back to desired position.
And if all this fails, it may be an alternative to delete/rename the file mp3tag.cfg
