I am trying to use Windows Task Schedule to open up Firefox BUT I need it to be open as a FULL SCREEN mode each time. When I try to CLOSE it in full screen mode (using f11 or otherwise), it DOES NOT open in FULL SCREEN mode the next time it opens. Any suggestions or arguments to help with this?

What's your computer system and Firefox version?

https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options

Unfortunately, there is no option to tell Firefox to open with a full-size window.

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

Search for the above files. Then rename or delete them. Restart Firefox.

I don't think that Firefox saves the full screen and maximize property in xulstore.json. What could work if to make the Firefox window as large as possible by dragging the borders.

You can search the Addons website for 'fullscreen': MPT Fullscreen https://addons.mozilla.org/firefox/addon/mpt-fullscreen/
