# Install/Update Mozilla Firefox conveniently and repeatably, allowing version selection

This was created as a workaround for https://github.com/psf/requests/issues/4032

This is really only useful if you have a sprawling application and/or many sessions
and you don't want to handle the NamedTemporaryFile solution outside of the Session
yourself

It's surprising at first that requests.Session doesn't provide the ability to specify
a StringIO (or other file stream like object) but when you see the OpenSSL interface
