The NoScript Firefox 57 supports executable web content. This web content makes use of JavaScript, Java, Flash, Silverlight, and other plugins. But the site that is being hosted needs to be trusted by its user. Also, it must be affixed as a whitelisted site. Nevertheless, it also offers distinct protection against the known security exploits in a web browser. NoScript grants their users high-quality protection against web-based attack vectors which include cross-site scripting, cross-site request forgery, clickjacking, and DNS-rebinding attacks as well.
A Detailed Overview On NoScript Firefox 57
The extension of NoScript created a hype among the users in the initial phase. It received mixed reviews from the Firefox users, but the confusion has now been settled. So in this context, we will explore the details of NoScript Firefox 57.
Interface
Mozilla has altered the interface of the NoScript in the latest version. While the previous version used a list view approach, the newer interface uses a matrix approach.
The current interface presents a toolbar at the top of the page. Underneath the toolbar is the list of domains. The NoScript lists the present domain first and then lists the third-party connections under it. Check the padlock symbol at the side of the domain. It denotes that the connection is secure with encryption because it uses HTTPS.
Establishing The Trust Levels
Each and every domain that is under the whitelist by NoScript provides a certain trust level.
- Default- Blocks your JavaScript along with the objects, media, fonts, and WebGL.
- Trusted- Lets you execute the JavaScript
- Trusted Temporarily- Lets the JavaScript run and load other elements for the new session.
- Untrusted- No access or permission for the website.
- Custom- In this case, you can choose to allow or disallow the elements.
The default preset permissions for NoScript are trusted, default and untrusted. You can also customize the default presets as per your choice. There are some elements that NoScript differentiates which are given below.
- Script- Several types of scripts which the site may execute.
- Object- Here, it is the tag of the HTML object.
- Media elements.
- The frame which your site is trying to load.
- Font elements
- WebGL elements
- Fetch requests that use the APIs.
Button Toolbar
The latest version of NoScript for Firefox shows several buttons in the toolbar. We have listed the buttons from left to right.
- Close- which is to exit from the Interface.
- Reload button for loading the page once again.
- Options button.
- Disable restrictions globally button.
- Disable restrictions for this tab button.
- Set all on the page to temporarily trusted button.
- Revoke temporary permissions button.
NoScript also has the feature of adding a context menu item to the right-click menu on its own. Moreover, when you click on the context menu, it displays the main NoScript interface on the user interface of the browser. Also, you can disable the context menu entry by navigating to the Options.
Usage Of NoScript
You need to understand the working of NoScript Firefox quantum. If you do not understand this, then you won’t be able to use the NoScript extension properly. The main functionality of NoScript is to show you the list of items that are blocked at the time of loading the sites in your Firefox browser. Once you click on the icon, it displays the connection and the trust levels of every website. If you do not let the execution of scripts, sites may be unable to start all the third-party connections.
If the site is working correctly, then it is not necessary to make any new modification to the trust levels. You may also find that at the time of the first connection, some features may be not working correctly. It can even come to your notice that some elements and scripts are blocked by default. Some sites use scripts for examining form submissions and playing videos for advertisements.
If you alter the domain’s trust level to either trusted or temporarily trusted, then it can allow you to load additional elements. Whereas, if the trust level is set to untrusted, then it will keep away more scripts. You must note that the trusted and the untrusted trust levels are the permanent changes and that they remain available as well.
Troubleshoot A Site
You may choose to troubleshoot a site when you find that the site functionality is not available. This may happen because the NoScript is blocking these sites. If you are choosing the option “allow all globally” in the NoScript button, then it can eliminate the protective shield of NoScript.
NoScript provides a feature of whitelisting all the sites that are safe to use by default. So, before you use them, check the option “per-site permissions” to be on the safe side. By no means, you can delete the sites that are on the list by default. Yet, you can alter the trust level of those sites from trusted to default or untrusted depending on your need. Nonetheless, if you have the latest version of NoScript, then you will find all the custom sites over there.
Options
The NoScript settings are distributed into four tabs. The functions of these four tabs are given below.
- General- Change the preset permissions to any option among Default, trusted and untrusted. Furthermore, you can enable the option “disable restrictions globally” and “temporarily set top-level sites to Trusted.”
- Per-site Permissions- It shows all the custom permissions including the Search option.
- Appearance- You can customize the NoScript interface by hiding the context, turning off the count badge and also enabling the list of full addresses in the permissions section.
- Advanced- You can look after cross-site scripting protection and also power on the feature of debugging.
