How to Block Intrusive Javascript on Chrome and Firefox

The method is quite simple and easy and you just need to follow simple guide that will help you to implement this. We have selected two extensions based on user rating, download rate and some of our personal experience and hope you will also like these extensions.

For Google Chrome
Google Chrome comes with a few extensions which are really good at blocking intrusive Javascript. These extensions will allow you to choose which script to block and allow. So, let’s have a look at some of the best extension which you can use to block intrusive javascript from Chrome browser.

ScriptBlock
For google chrome, we have one extension that you can easily use to better manage your scripts on the browser. And the extension is ScriptBlock. The script block is an extension that provides better control of javascript, iframes and other unwanted content. It even can mitigate cross-site-scripting(XXS) attacks and drive-by-downloads. ScriptBlock works perfectly together with other extensions like AdBlock, AdBlock Plus or Ghostery. You can add your trusted sites to a whitelist, so they will not be affected by ScriptBlock. Simply open the above-shared link and then download and install the app and then you will see this extension will be blocking these scripts.

Using Scriptsafe
ScriptSafe is another interesting Google Chrome extension that works not only on Google Chrome but also on Chromium-based browsers like Vivaldi. The interface of ScriptSafe is very clean and it blocks nearly all scripts by default. Sometimes, this feature breaks the web page, however, the extension also provides users an option to allow script.Not only that, you can also add the script to ‘Trust’ which will not block the script. You can even deny any particular script which will force the extension to block the script on any webpage. ScriptSafe also shows users the list of blocked content. Basically, it gives users the ability to block and allow scripts.

#2 Mozilla Firefox
Just like the Google Chrome, Firefox also has add-ons which you can use to extend the features of the browser. Firefox also has a couple of add-ons that can help you to block intrusive Javascript on the browser. So, let’s have a look at some of the best add-ons which you can use to block intrusive javascript from Firefox browser.

Using Toggle JS
Similarly like Chrome, we have one great add-on for Firefox that is Toggle JS. A simple toolbar button to quickly toggle javascript between enabled or disabled. A green shield is shown when javascript is enabled and a red shield is shown when it is disabled. You just need to simply visit the link shared above and then download and install the extension.
Using NoScript
NoScript is very much similar to the ScriptSafe which is an extension for Google Chrome browser. The NoScript for Firefox is one of the best addons which you can use to block intrusive Javascript on firefox browser. By default, the add-on blocks all the scripts that load automatically after opening a webpage.However, the addon gives users an option to unblock the blocked scripts. The addon blocks scripts by domain and it gives users an option to temporarily allow a script. You can also permanently allow all scripts on the page by hovering over ‘Allow all on this page’
