Unlocking about:config Minimum TLS Preference
I need to edit minimum TLS version in order to remotely manage order device that use TLS 1.0. I'm using FireFox 102 and the security.tls.version.min is grayed out and I cannot edit.

For the desktop Firefox the TLS 1.0 and TLS 1.1 have been deprecated since Firefox 78 Release and should not be used now days.

You can still enable TLS 1.0/1.1 via about:config although this is not recommended and you should only flip the pref when you need to access this device/website and reset the pref to false once you are done.
- about:config => security.tls.version.enable-deprecated => true
You can open the about:config page via the location/address bar. If you get the warning page, you can click the "Accept the Risk and Continue" button.
