In fact, setting up and working with NoScript is no more difficult than setting up any software Firewall (firewall) in learning mode. The main thing is to understand how it works
Maximum Security
We hover over the NS icon in the extensions panel - a menu window with a list of domains and blockings rises - click on
Settings
Main -
Checkboxes should be on:
Open extension menu when hovering mouse over icon
Automatically update dependent pages when rules change -
in this position, sometimes you need to click on the extension bar next to the NS icon for the permission changes on the page to take effect. This is required if for some reason the page did not reload itself with the new settings, or when a temporary global permission is given
List of sites or IP addresses with full permissions. It is better not to add addresses manually, but to use full permission directly on the web resource page. This is done because by giving full permission on the page, NoScript will remember all the active content that was on the page at the time the setting was changed. And this is very useful for the subsequent diagnostics of the site for the appearance of new scripts or objects. If you manually enter the address directly into the white list, then changes will not be tracked, and if a malicious or aggressive code is added tomorrow on a trusted clean site TODAY, you will not know about it or you will find out, but it will be too late. Better List leave only for editing in the sense of deleting already unnecessary addresses
Built-in objects -
Additional restrictions for untrusted sites- checkboxes should be on the following items:
List of bans
Prevent display of Java elements
Prevent display of Macromedia Flash elements
Prevent display of Microsoft Silverlight items
Prevent display of elements of other plugins
ban
Block any object from untrusted sites -
all of the above items on sites without permissions will be blocked by default
Highlight locked objects with an icon with a frame -
on the page, instead of iframes, flash objects, fonts and other elements, there will be NoScript icons when hovering over which information about the object will be displayed
Confirm temporary unblocking of an object on the page -
If you want to allow flash or iframe on the page, for example, you will receive a window with info about the object and a question: do you really want to allow ...
ClearClick protection on pages -
must have checkboxes in both positions
These are the most stringent protection settings for all untrusted sites where scripts, flash objects and other elements must be manually unlocked by looking at the domains from which they are broadcast or downloaded. IFRAMEs should only be allowed as a last resort if you are 100% sure of the domain. This is the most dangerous tag!
Optional -
Untrusted- checkboxes should be on the following items
Additional restrictions
Prevent the website from using the setting
Prevent display of XSLT elements
Apply JavaScript link repair algorithm
Trusted -
you can leave the checkbox to allow local links
leave both checkboxes by default and do not touch anything
HTTPS- Cookies -
check the box for automatic cookie management. You can add to the list sites for which you want to encrypt cookies, and sites for which you want to ignore cookies.
ABE settings and External filters can be left untouched and left as is
If you do not need strong and reliable protection and want to change these settings, then remember that IFRAME and JAVA, as well as elements of other plugins (see picture) should always be blocked. These settings should not be removed.

Mozilla Firefox has built-in protection for your computer while surfing the web. However, they may not be enough, and therefore you will need to resort to installing special add-ons. One of the add-ons that will provide additional protection for Firefox is NoScript.
NoScript is a special add-on for Mozilla Firefox, aimed at strengthening the security of the browser by prohibiting the execution of JavaScript, Flash and Java plugins.
It has long been known that JavaScript, Flash and Java plugins have many vulnerabilities that are actively used by hackers when developing viruses. The NoScript add-on blocks the work of these plugins on all sites, except for those that you yourself add to the trusted list.
You can either immediately proceed to download and install the add-on using the link at the end of the article, or find it yourself.
To do this, click in the upper right area on the web browser menu button and open the section "Additions" .
In the upper right corner of the window that appears, enter the name of the add-on you are looking for - NoScript .
The search results will be displayed on the screen, where the extension we are looking for will be displayed as the main one in the list. To add it to Firefox, the treasured button is located to the right "Install" .
You will need to restart Mozilla Firefox to complete the installation.
How to use NoScript?
As soon as the add-on starts its work, its icon will appear in the upper right corner of the web browser. By default, the add-on is already doing its job, and therefore the work of all problematic plugins will be prohibited.
By default, plugins do not work on absolutely all sites, but, if necessary, you can create a list of trusted sites for which plugins will be allowed.
For example, you went to a site where you need to allow plugins to work. To do this, click on the add-on icon in the upper right corner and in the window that appears, click on the button "Allow [site name]" .
If you want to create your own list of allowed sites, click on the add-on icon and in the pop-up window, click on the button "Settings" .
Go to tab "White list" and in the field "Website Address" enter the URL of the page, and then click on the button "Allow" .
If you need to disable the add-on altogether, there is a separate block in the add-on menu that allows scripts to work temporarily, only for the current site or for all websites.
NoScript is a useful add-on for the Mozilla Firefox web browser, with which web surfing will become much safer.
NoScript- Firefox extension, blocking the execution of JavaScript, Java applets, Flash and other potentially dangerous components of HTML pages until the user allows their execution on this site or globally.
The Mozilla Firefox browser takes care of the user's security. The browser has built-in protection for your computer. Alas, this is not always enough. However, trouble is easy to help - install an extension that will protect you while surfing the net. One of the good options for add-ons that protect you while working in Firefox is NoScript.
The add-on provides additional security by blocking JavaScript, Flash and Java plugins. It is they who have a large number of vulnerabilities, which are enjoyed and used by those who create all kinds of malware. You can download NoScript for free from our website.
Key features
The add-on icon (blue letter S) will appear in the upper right corner of the browser. NoScript starts automatically, you do not need to run it. However, you can still control its operation. In particular, add to the "White List" sites in which you are sure, and where "suspicious" plug-ins do not need to be blocked. This is very convenient - after all, some sites without Flash and Java will simply open incorrectly.
Even a child can download NoScript in Russian. This is an official add-on for Mozilla Firefox, so it's in the catalog. Find the "Add-ons" section in the menu, enter in search string the name of the extension, and after its "detection" click the "Install" button. NoScript will be enabled automatically the next time you open your browser.
Extension pros and cons
As with any NoScript utility, it has its own advantages and disadvantages:
- Additional protection when surfing the Internet.
- Ease of use.
- Instant installation.
- You can download NoScript for free.
- For Mozilla Firefox only.
- Some sites will not open correctly before being added to the White List.
System requirements
- Windows Server 2003 SP1, Win 7, Win 8, 8.1, Win 10;
- Mac OS X 10.9, 10.10, 10.11, 10.12;

What browsers does it work with
With NoScript, you can allow JavaScript, Flash, Java and other plugins to run in and . only for sites that you specify in the settings.
How to install
The settings can be made in the extension tabs.
Conclusion
The tool provides additional protection for Firefox. Allows JavaScript, Java, and other active content to run only for trusted domains of your choice. Provides security for working in the "zone of trust", protects against scripting attacks (XSS), cross-zone DNS spoofing / CSRF attacks (hacker routers), and ClickJacking attacks. Implements DoNotTrack protection by default. Experts agree: Firefox is indeed safer with NoScript.
One of the main reasons I use on my computer Firefox browser, and not any other, is a NoScript extension that is only available for this browser.
NoScript, as its name suggests, blocks scripts and prevents them from running automatically on most sites. This significantly increases security, since most attacks carried out from sites use scripts to achieve results. The extension also improves page load time, because when NoScript is enabled, much less content needs to be loaded.
The disadvantage is that the functionality of some sites may stop working. Since scripts are blocked by default, the site may stop working altogether, or work partially with NoScript installed.
Extension offers additional settings to address these issues. You can allow scripts to run temporarily or permanently on certain sites.
Another problem is that scripts are blocked at the domain level. Most websites download scripts from various sources. Scripts from your own domain come first, followed by scripts from third-party servers, for example, to display ads, to collect information, and even to use a server-hosted version of jquery.
It is very often difficult to determine which scripts are necessary for the basic functionality of the site, and which are not. It will be especially difficult for Internet users who have little experience in domains, website technologies and scripts.
Setting NoScript
NoScript comes in pretty successful configuration. You can use it as is, but if you want to get the most out of this addon, then you should go through the settings at least once to make sure everything is set up exactly the way you want.
As I mentioned earlier, NoScript blocks script execution on most sites by default. The extension comes with a whitelist of domains, which means that sites that are hosted on this list can download scripts that are hosted on their own domain without any problems.
Clue: NoScript distinguishes between root domains and subdomains. Domains such as addons.mozilla.org and mozilla.org are treated as distinct by the extension.
Whitelisted domains include: addons.mozilla.org, google.com, googleapis.com, live.com, hotmail.com, outlook.com and paypal.com.
You can use any whitelisted domain in NoScript settings.
You can also import or export selected domains. This is useful if you use Firefox on multiple devices and want to have the same whitelist.
The second configuration change you can make concerns the NoScript icon. You can place it in a place where you have easy access.
I put my icon on the addon bar, but after the bar was removed from Firefox Australis (version 29), you can put the icon on the browser's main toolbar.
The other option you have is to use the context menu. NoScript adds an item to Firefox's right-click context menu that can be used to block and allow sites, and to open additional features extensions.
If you are using an icon, you can also use multiple useful features, built into the extension by the developer. To allow all scripts on the current site, middle-click on the icon. In addition, you can set the left mouse button to block or allow the top level site according to the settings in "General".
You may notice that a message about blocked scripts is displayed on the screen in notifications. This can be useful, especially if you're using the context menu exclusively, but if you're using an icon, it will let you know what's happening.
I prefer to remove notifications as they block part of the screen without telling me anything I don't already know.
You can turn off notifications in the extension options.
Instead of displaying a message, you can activate an audio signal. I don't recommend you do this, especially if you're loading a lot of sites while you work.
Let's go back to the NoScript list that is displayed when you click the left or right mouse button on the icon.
The menu displays all the scripts that the site is trying to load. The root domain is always at the top of the list, while other domains are placed at the end.
Advice: Resolving the root domain is usually sufficient for full site functionality. I recommend that you start by downloading sites without using the whitelist to see if the site works with the default settings or not. If not, then most likely the site needs to load a script in order to function properly. There are exceptions to this rule. You may notice that some sites use content delivery networks that you need to approve, and some sites may download libraries from third party sites like jquery.
You can middle click on any domain to run a security check. When you click on the middle button, you will be taken to a page on the NoScript site that links to several popular security services such as Web of Trust, McAfee Site Advisor, and hpHost.
Use these services to validate a domain before allowing scripts to be loaded. Alternatively, you can use the manual check on Virustotal.
Advice: right click on any Domain name to copy it to the clipboard.
Digging Deeper
Let's dig a little deeper. NoScript offers users more than just script blocking. It can be used to process embedded content.
This kind of content is default for sites not on the whitelist, but not blocked for sites temporarily or permanently on it.
This means that content like Java, Flash, Silverlight and other plugins will load on whitelisted sites by default. If you do not want this to happen, you must make the following NoScript configuration change in the tab Setup > Embedded Objects.
Here is an example where this can be useful. Let's say you need to whitelist a site in order to be able to access all of its functionality. By whitelisting it, you may inadvertently also allow Flash ads, videos, and other content that requires the use of plugins to play.
Of course, it makes sense to do this with allowing content for whitelisted sites like YouTube, because you're visiting it for the video. However, if you apply restrictions for whitelisted sites, it will improve the security and privacy of your computer.
It means large quantity clicks to allow content, but it's a fair trade-off for security.
If you activate this function, you will receive a confirmation message each time you click on blocked content. You can turn it off by turning off the "Ask for confirmation before temporarily unblocking an object" option.
Note: you can set up prohibited items on the same page. Theoretically, it is possible to make some content available and some blocked at the same time. One of options is to allow Flash and disable everything else.
Additional options
At first glance, the advanced options can look intimidating, as you will come across a lot of technical terms such as XSLT, XSS, ABE. It even mentions ping!
In truth, all of these options are best left alone, of course, unless you require specific features.
There is one feature that may be of interest here - the protection of cookies. You can set NoScript to provide encryption for cookies set over HTTPS for certain sites.
Some web services set cookies over a secure connection, but do not mark these cookies as secure. As a result, a request for these cookies from the same domain will succeed even if it comes from a non-HTTPS page.
However, you may encounter problems on some sites and you will no longer be able to log in to these sites, or you will be automatically logged out when you switch pages.
You will find information about these issues in the Firefox web console that appears after pressing Ctrl-Shift-i. Use the information you receive to add exceptions to the rule.
There are other features worth looking at as well. These are the prohibition of bookmarklets on untrusted sites, the permission of local links for trusted sites, and the prohibition of attempts to fix JavaScript links.
The NoScript extension helps to prevent potentially dangerous actions on the pages of sites on the Internet. When visiting various sites on the Internet, on the web pages of the visited sites, various potentially dangerous actions are often performed, which are performed by components that are located on the open web page.
In order to protect yourself from such actions when using the Mozilla Firefox browser, the NoScript add-on is used, with which you can block the launch of potentially dangerous scripts that may occur on the web page you have visited.
By installing the NoScript extension, you will be protected from executing scripts on the web pages of the sites you visit, except for those sites on the pages of which you allow them to be executed. This extension also protects against XSS attacks and ClickJackihg, disables Flash, hides the computer's IP address.
Script, or script, is a regular program code placed on a web page that allows you to perform any action on this web page. By using various scripts a beautiful animation can start, registration occurs mailbox, chatting on the forum, etc.
But there are also malicious scripts embedded in web pages that download various viruses and other malicious code without your knowledge when you open or visit an infected web page.
The NoScript extension allows you to disable scripts for untrusted sites, thus preventing the possible execution of malicious scripts on the web page you visit. On reliable sites, the degree of reliability of which you determine yourself, the execution of scripts will not be blocked.
NoScript add-on
To install the NoScript add-on, you need to click on the "Firefox" button, and in the "Settings" menu, click on the "Add-ons" button. In the search box "Search among extensions" you need to enter the expression "NoScript". On the page of this extension, you need to click on the button "Add to Firefox" => "Install now" => "Relaunch now".
After installing the extension, you can go to "Settings" in order to look at the settings of the NoScript add-on, which are made by default. In the "NoScript Settings" window, in the "General" menu, you can check the item "Allow JavaScript execution for all websites from bookmarks".
If you have a lot of bookmarks and you trust these websites, then you don't have to set up separate rules in this add-on for each site you bookmark.
The menu "White List" already contains some sites included there by default, you can add selected websites to this list yourself by entering the site address in the "Website Address" field, and then click on the "Allow" button. This action can also be performed using context menu.
The remaining settings of the NoScript add-on can be left unchanged and the default settings of this extension can be left.
After switching on NoScript extensions At the very bottom of the Mozilla Firefox browser window, a panel with an add-on icon in the form of the letter "S" will appear. By clicking on the "Settings" button on this panel, you can give a command to perform the actions you have chosen.
You can close this panel and perform all actions related to the NoScript add-on from the context menu by selecting the desired action to allow or block the execution of scripts on a specific web page.
If you disable scripts on a particular web page, you will not be able to see many of the objects that may be on that page, watch flash videos, some ads, and other web page content, unless you temporarily allow some scripts to run on that page.
You can add a website to the "White List" of trusted websites, on the pages of which the execution of scripts will be allowed without the interference of the NoScript extension in this process.
You can disable the execution of Java scripts (JavaScript) using the Mozilla Firefox browser itself.
To do this, click on the button "Firefox" => "Settings" => "Settings". In the "Content" tab, you need to uncheck the box next to the "Use Java Script" item. After that, on all web pages that will be opened by the browser, the use of scripts will be prohibited.
The difference in using this method of disabling scripts, from the NoScript add-on, is that you will not be able to control the inclusion or disabling of scripts on a particular web page.
Article Conclusions
NoScript's extension Mozilla browser Firefox disables JavaScript execution, Falsh, hides IP address. The user can independently enable the execution of individual or all scripts on specific web pages.
