He worked with Mozilla to create the new version of NoScript and implemented options to migrate settings from classic versions of NoScript to the new version.
The initial version received mixed reviews. Some users heralded the effort and were happy that NoScript was available for Firefox 57 and newer, others did not like the new user interface or criticized missing functionality.
Now that the dust has settled, it is time to publish an updated guide for NoScript for Firefox 57 or newer.
The main interface of the extension changed completely in the new version. The classic version of NoScript listed connections in list view on activation, the new version of NoScript uses a matrix instead similarly to how uMatrix handles connections.
The interface displays a button toolbar at the top and below it the list of domains. NoScript lists the current domain at the top all the time and below it the third-party connections of the page.
The padlock symbol displayed next to domains indicates that the connection to it uses HTTPS. Note that the padlock symbol is not displayed for some trust levels.
Each domain listed by NoScript in its interface has a trust level associated with it.
Each domain listed by NoScript has one trust level associated with it. A click on another trust level in a row switches it to the new one automatically.
The NoScript options reveal the preset permissions for "default", "trusted", and "untrusted".
There you may also change the default presets by adding or removing checkmarks. The elements that NoScript distinguishes between are:
Seven buttons are displayed on the button toolbar in the latest version of NoScript for Firefox. They are, from left to right:
NoScript adds a context menu item to the right-click menu automatically. It has limited use though; a click on it displays the main NoScript interface at the top of the browser UI. You can disable the context menu entry in the options.
Understanding how NoScript trust levels work is essential to using the extension to its fullest potential.
NoScript indicates blocked items in its icon when you load sites in the Firefox browser. A click on the icon displays the connections the extension recognized and trust levels for each site. Note that these may not be all connections a site makes. Since you don't allow the execution of scripts by default, sites may not be able to initiate all third-party connections right away.
If you allow scripts to run on the main domain, you may notice that it attempts to make additional connections when those get loaded.
Tip: Hover over any domain listed by NoScript and click on it to open a page that is full of links to privacy and security services only to display information about the domain.
It may not be necessary to make any changes to trust levels if the site functions properly. You may notice however that some features may not work properly on first connect.
Since scripts and other elements are blocked by default, you may notice all sorts of issues related to that. Sites use scripts and other elements for a variety of things, from verifying form submissions and playing videos to often unwanted things such as advertisement or tracking.
Changing a domain's trust level to "trusted" or "temporarily trusted" allows it to load additional elements whereas a trust level of "untrusted" prevents even more elements.
Note that trusted and untrusted are permanent changes that remain available.
Troubleshooting a site comes into play when you notice that site functionality is not available and suspect it is because of the protections that NoScript provides.
You have a couple of options to deal with the issue. You could temporarily allow a domain or use the custom trust level to set permissions individually for elements.
I'm not a fan of using the "allow all globally" or "allow all for the tab" options as they are often too broad. While they are comfortable, as you only need to press some buttons to get sites to work, using them eliminates most of the protective functionality of NoScript.
NoScript comes with a whitelist that includes sites by default. You may want to check it in the options under "per-site permissions" to make sure that you trust them all. There is unfortunately no option to remove sites that are on the list by default but you can change the level from trusted to default or even untrusted.
If you migrated from a previous version of NoScript, you should see all custom sites there.

The options are somewhat limited at this point in time especially when you compare them to the options of the classic version of NoScript.
The NoScript settings are divided into four tabs right now that offer the following functionality:
Options can be reset, imported, or exported.
