Learn how to allow or block JavaScript in Firefox. JS makes the site interactive, just as it is also prone to hacking.
Today almost all browsers support JavaScript (JS). It is a programming language used by web developers to make their web pages more interactive by adding functionality such as a menu, sounds, animations, and many other cool features. Occasionally we may need to disable it for security reasons.
Javascript is introduced to improve the user experience, but it has its drawbacks. The most common demerit of Javascript is advertising popups and other irrelevant information that needs to be closed.
I have always found irrelevant information very annoying and irritating, so I prefer to disable it. It is also misused by a hacker to hijack our browser and inject the malware. Disabling Javascript can solve many problems. It will also improve browser security by eliminating the possibility of hijacking.
The main disadvantage of disabling JavaScript can damage a site that is built exclusively on it. You may also lose the interactive feature offered by JQuery (one of the JS libraries).
Block Javascript in Firefox
Javascript can cause your browser to lag at times due to its heavy nature and high processor requirement. By disabling JavaScript for the site, you will be able to browse the simplified version of the web page and fix its security issues.
Here are the steps to block JavaScript in Firefox:
start the in the computer.
Enter the command about:config in the URL bar.
Click the button Accept risk and continue .
Search for javascript.enabled in the search bar about:config .
Click the button to change the value to false.
This will disable JavaScript in your Firefox browser and it will no longer run anywhere. As I mentioned earlier, this will break sites that rely heavily on JS features.
Allow JavaScript in Firefox
Now, if you have disabled Javascript, you may notice that certain websites may not work. This is expected behavior as these sites require JS to be executed on the backend to perform tasks. You have no other options except to allow JS to run in Firefox.
Here are the steps to allow Javascript in Firefox browser:
start the Firefox computer browser.
Enter the command about:config in the URL bar.
Click the button Accept risk and continue .
Search for javascript.enabled in the search bar about:config .
Click to change the value to true.
Once you’ve made the changes, simply restart the Firefox browser and verify that the JS is running and the sites are no longer corrupted.
Conclusion: Firefox Javascript Settings
You can disable Javascript to get rid of anonymous ads that appear and ruin your browsing experience. It also helps keep you protected from digital hijackers.
However, few websites will not work if you have Javascript disabled. Therefore, it is suggested that you allow Javascript before browsing those sites so that they load correctly.
I kept my JavaScript enabled as I don’t want to break every website I browsed.
I wish Firefox would provide a robust option where we can manually allow or block JavaScript from running on sites. I really like the way Chrome has handled the JS options and has the dedicated settings page.
