What's your computer system and Firefox version?
https://support.mozilla.org/en-US/kb/changes-toolbars-and-window-sizes-are-not-saved You may have corrupt xulstore.json or Localstore.rdf files.
Close Firefox. Open your file browser to this hidden location:
- Mac: *~/Library/Application Support/Firefox/Profiles
- Linux: *~/.mozilla/firefox/Profiles
- Windows: %AppData%\Mozilla\Firefox\Profiles
- Windows XP: C:\Documents and Settings\<user>\Application Data
Search for the above files. Then rename or delete them. Restart Firefox.
