  1. Open the Add-ons Manager, Extensions category either from the ≡ Menu Button or by pressing Ctrl+Shift+A (Mac: Command+Shift+A).
  2. Next to ShowIP, click the Disable button.
  3. Type about:support into the address bar and press Enter.
  4. Click the Show Folder button. A Windows Explorer window with your profile folder opens.
  5. Exit Firefox.
  6. In the Windows Explorer window, delete the localstore.rdf file.
  7. If the problem persists after you restart Firefox, another one of your add-ons is to blame.

Thank you. Right after I disable ShowIP plugin, panel at the bottom is no longer visible and customization works fine.
