ABOUT

about:config settings to harden the Firefox browser. Privacy and performance enhancements.
To change these settings type 'about:config' in the url bar. Then search the setting you would like to change and modify the value. Some settings may break certain websites from functioning and rendering normally. Some settings may also make firefox unstable. I am not liable for any damages/loss of data.

Not all these changes are necessary and will be dependent upon your usage and hardware. Do some research on settings if you don't understand what they do. These settings are best combined with your standard privacy extensions (HTTPS Everywhere No longer required: Enable HTTPS-Only Mode, NoScript/Request Policy, uBlock origin, agent spoofing, Privacy Badger etc), and all plugins set to "Ask To Activate".

As far as I am aware the time has come and as of Firefox 72 XUL has been stripped from firefox and so the method used to inject this scrollbar theme is no longer supported -- reference the following for future scroll themes:

Mozilla is currently working to phase out the APIs used to make this theme work. I will try to maintain each version until that time but eventually there will be no workaround. When that time comes there is a new, but more limited api for applying simple themes to scrollbars. In nightly I am currently using the following userContent.css

:root{
	scrollbar-width: thin;
	scrollbar-color: rgb(82, 82, 82) rgb(31, 31, 31);
}
