A lot of Windows applications launch with the size of the window as it was when closed. Every time I Iaunch Firefox, I have to resize the window to fit my needs. Doesn't Firefox preserve those conditions for the next time the application is launched?

Thank you for your time.

Close Firefox. Open your file browser to this hidden location:

  • Windows: %AppData%\Mozilla\Firefox\Profiles
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
  • Windows XP: C:\Documents and Settings\<user>\Application Data

\Mozilla\Firefox\Profiles\

Search for the above file. Then rename or delete it. Restart Firefox.
