I think it's fair to say that personal computers have become the
most empowering tool we've ever created. They're tools of communication, they're tools of creativity, and
they can be shaped by their user.
-Bill Gates

Userscripts are a very useful tool if you play torn on your PC. Userscripts when installed modify the way websites are laid out, they add or inject things on the page, change styles and colors of the page, and a lot more. There are several userscripts avail for Torn and they are totally legal to use. You will not get banned for using scripts as long as they are created within the guidelines of whats allowed by Torn. You can read more on those guidelines here.
In order to use userscripts you must first install an extension for your browser. Tampermonkey for Chrome Browser.Greasemonkey for Firefox Browser.Tampermonkey for Opera Browser.
NOTE: There is an extension that has incorperated many userscripts into it. This extension is called Torn Tools. You can find this extension for Chrome and Firefox. More info.
There are a couple places to find userscripts. One of them is Greasyfork. A lot of these scripts are outdated and don't work anymore, however there are still a few that do.
