Java plugin for Mozilla Firefox

Java Firefox is a fairly popular technology that has provided the basis for many web pages and personal computer programs. However, users often encounter that Java content is not displayed in the browser.

Download Java 64 bit

Why 64 bit

It is worth noting that there are different versions of Java - for developers and ordinary users, which allow you to use the minimum and maximum resources of the computer's RAM.
The 64-bit version of Java is considered optimal for the smooth operation of most modern programs. Users often complain that Java files are marked as suspicious by most antivirus software. The fact is that the popularity of 64-bit Java is constantly growing, so it is not surprising that attackers often try to use this fact for their own purposes. To protect your software, it is recommended to regularly update your software by downloading new versions of Java that are protected against all currently existing viruses.

How to install Java on a computer?

Before downloading Java 64 and installing a new program, you need to go to the control panel of your computer and make sure that all old Java elements are removed. To do this, you can use the standard “uninstall programs” tool, and then check the result by opening and manually emptying the folder with the corresponding name on the local drive C, in the Program Files folder. One more nuance - it’s worth going to the computer properties, or rather, to the additional system parameters and in the “Environment Variables” tab, delete the path to the old version of Java, if it is registered there.

Having the latest version on the device will ensure the correct operation of many programs that use components written in java in their work. The absence of software on the device will lead to the inoperability of numerous programs.

Downloading the current version

The next stage of installation is downloading the software. It is worth noting that by downloading a standard program in one click from the official website java.com you will receive a 32-bit version, which is not able to allocate more than 1 gigabyte of RAM for a game, chat, application, etc. It will be much more productive from an operational point of view to download Java 64 bit. If the program is not needed for development, but simply to run in Java, you need to find the Java JRE (Java SE Runtime Environment) version of the program, and then select the 64-bit version and download it to your PC.

To avoid installing unnecessary search bars and additional browsers, watch for pop-ups and, if necessary, uncheck the boxes next to programs that you are not interested in installing.
