Command Line Parameters
|
|
=======================
|
|
|
|
Firefox recognizes many (many!) command line parameters. Overview
|
|
documentation of these parameters lives here.

Known parameters

* - Parameter
|
|
- Description
|
|
* - ``-osint``
|
|
- On Windows, ``-osint`` serves two purposes. Most importantly, it signals
|
|
that the command line is untrusted and must be sanitized. Command lines
|
|
with ``-osint`` are rejected unless they are of exactly the form
|
|
``firefox.exe -osint -url URL`` or ``firefox.exe -osint -private-window URL``:
|
|
refer to `the EnsureCommandLineSafe function
|
|
<https://searchfox.org/mozilla-central/rev/ead7da2d9c5400bc7034ff3f06a030531bd7e5b9/toolkit/xre/CmdLineAndEnvUtils.h#196>`_.
|
|
These command lines are produced by apps delegating to Firefox, and the
|
|
resulting URL may not be correctly quoted. The sanitization process
|
|
ensures that maliciously chosen URLs do not add additional parameters to
|
|
Firefox. Secondarily, the ``-osint`` parameter signals that Firefox is
|
|
being invoked by Windows to handle a URL: generally a registered file
|
|
type, e.g., ``.html``, or protocol, e.g., ``https``.
