How To Enable/Disable JavaScript In Your Web Browser
JavaScript is a standard programming language that can be included in web pages to provide functionality such as menus, sounds, and other interactive features. By default, Firefox enables the use of JavaScript and requires no additional installation.
Do you have to disable JavaScript, for some reason(see, Why do people disable JavaScript
)?
Here is the step-by-step instructions for disabling JavaScript in your browsers. By the way, Java and JavaScript are two different things, so make sure that you're looking at the correct language.
TIP : If you're a web developer, you are adding JavaScript to your pages, it's a good idea to view your pages with JavaScript disabled, so you can get an idea what users without JavaScript enabled browsers would see.
WARNING : Please note that you may loose some of the web page functionality by disabling JavaScript.
Disable JavaScript In Firefox
Step 1 :
Type about:config in your location bar and press "ENTER" button..
Step 2 :
Now confirm the warning message..
Step 3 :
Now , type "javascript.enabled" in search box..
Now change the value of javascript.enabled to false (The default value is "true".. to change it to "false", Right click on it and select toggle option.)
To enable it again, toggle the value back to its default value.. (i.e) set the value as "true"

Enable/Disable Backspace as 'Go Back' Shortcut in Firefox
In Firefox on Windows operating system, if you press the `backspace` key, it will take you one page back from current web page, an action that similar to when the both Firefox and IE browser's "Back" button, while `Shift+Backspace` will go forward. The backspace key is mapped to "Back" function in Firefox for Windows is for consistency with Internet Explorer.
On the other hand, Firefox in Linux by default does not map the backspace key to "Go Back" function to improve consistency with other applications running on Linux. Instead, the page will scroll up or down (when pressing Shift+Backspace key together).
The backspace as Back button feature can be easily turned on or off depending on user preference. Thus, Firefox for Windows users can disable the back function mapping to backspace key, and Firefox for Linux can enable the backspace to map to Back function easily, by using the following Firefox preference.
Step 1 :
Type about:config and then press Enter key in Firefox Location Box..
And then confirm the warning message.
Step 2 :
Then type "backspace" in search bar and locate the following preference name: browser.backspace_action
Right click on it ,select "Modify" option
and change the browser.backspace_action value to one of the following values (as per your need):
Set value as 0: If you want to set backspace key as 'Go Back' short cut. (Default in Windows)
Set value as 2: If you want disable Backspace as shortcut for 'Go Back' . (Default in Linux)
Firefox 46.0 Released with the awaiting GTK 3 integration on Linux , more safe JS execution and much faster experience...
Mozilla released Firefox 46 with GTK 3 Integration , More Secure JS execution environment and many fixes to screen readers ,web RTC and many other svg fixes... read what things have changed in FF46..
April 26, 2016, saw the official release of Firefox 46.0, the latest stable release of the popular open-source browser. As firefox is a mainstay of many Linux desktop distros, plenty of users will be keen to see how these changes will impact their favorite browser.
As is often the case, a number of the updates apply fixes to edge cases and obscure bugs that most users won't notice. Nevertheless, these fixes are important. But 46.0 isn't just about obscure bugs nobody cares about, it also brings a number of security and UI improvements that will be welcome to many GNU/Linux users.
This version of Firefox brings GTK3 integration, which the Linux world has been awaiting for some time. GTK3 is the widget toolkit that powers several popular desktop environments, including GNOME, Cinnamon, LXDE and Mate. Incorporating the same toolkit into the browser means tighter integration and better support for customization.
The change is not just cosmetic either. Older machines sometimes struggle to run multiple UI libraries at the same time, and browsers already are notorious memory hogs. Upgrading to 46.0 could make your browsing experience smoother and faster.
Security is a vital issue and one that often clashes with feature-rich applications. This is definitely true when it comes to Web sites and Web applications. Modern sites tend to be very JavaScript heavy, with rich interfaces that offer native-like performance. Unfortunately, allowing JavaScript code to execute in the browser opens a number of security weaknesses that clever cyber-criminals can exploit. And, that's one reason why many security-conscious users choose to deactivate JavaScript.
Mozilla has taken a step toward making JavaScript a more secure platform with a significant change to the way memory is allocated by the SpiderMonkey JavaScript compiler.
