To continue, you must enable javascript. How to enable Java in different browsers

Beginner users often confuse or mismatch programming languages such as Java and JavaScript. This is due to their similar name, which evokes corresponding analogies. The only thing in which they are similar is the goal of making familiar web resources more convenient to use.

In this article, we will look at the differences between these programming languages and figure out how to activate Java in browsers if a plugin or script was accidentally disabled.

What is the difference

Let's start with a simple explanation of the difference between the two technologies given above. Java is a technology created to develop applications that can run offline or through browsers.

Regarding JavaScript, everything is similar, except battery life. This technology is designed to work only with browsers. The script is initially placed in HTML files where it provides stable work and the exchange of data between web pages and the browser.

To supplement the information received, we will give an example of the main differences between these languages.

Unlike Java, JavaScript comes in text format, which is much easier than carrying out additional compilation.
The reliable operation of each technology lies in connecting different modules.
The operating algorithms of the languages are completely different and have practically nothing in common.

Working with the Java Plugin

Before you start working with the plugin, you will need to download it from the official source located at https://java.com/ru/download/. As a precaution, disable your antivirus's firewall, otherwise there is a chance of your download being blocked.

As soon as you follow the link provided, a window will open where there will be a red button with the inscription “Download Java for free”.
Click on it and wait for the download to finish.
Run the source file.
A small launcher window will appear, where you need to click “Install”.

After a short installation, the plugin will be available for use on your computer.

How to enable Java in the browser

Installing Java only solves the main problem in gaining access to the plugin. Now you need to check its functionality through the browser.

Internet Explorer

On the right top corner There is a gear that you need to click on.
A small menu will appear, select Internet Options.
Here you need to find the “Security” section and click on the “Other” item.
Rotate the window that appears until the talking block “Run scripts” appears in front of you Java applications».
You can enable it using the checkbox on the left.
The “OK” key will allow you to save the new settings and exit.

Google Chrome

The project developers limited access to working with plugins after the release of version 42 of the browser in 2015. In simple words, it will not be possible to launch Java using available tools.

Firefox

This web browser left users the opportunity to independently adjust many aspects of the program.

First of all, go to your browser settings.
Select "Tools" and then go to the "Plugins" block.
Here is the self-explanatory name “Java”. You need to click on it.
Pay attention to set value. For the extension to work, the “Always Activate” or “Request Activation” option must be set. It changes depending on the user's wishes.

How to enable JavaScript

Many sites resort to using Javascript in order to provide more features to their users. Let's find out how to enable this feature in popular browsers.

Google Chrome

Go to “Settings” using the context menu in the form of three points located in the upper right corner.
Scroll down the window and open "Advanced Settings".
In the “Privacy and Security” block that appears, select “Content Settings”.
Pay attention to the “JavaScript” item and open it.
There should be an active toggle switch opposite the inscription “Allowed”.

When making changes, be sure to restart your browser.

Internet Explorer

Go to the system settings using the gear icon.
Go to the "Internet Settings" section.
From here, navigate to the "Security" block by clicking "Advanced" here.
What is important to us here is the block with the self-explanatory name “Scripts”. It contains the “Activate Scripts” section, which should be in the “Enabled” state.
An activation window will follow, where you just have to click “Yes”.

As in the previous case, you must restart your browser for the changes to take effect.

Mozilla Firefox

In this case, everything is much simpler compared to the options above.

Open the Tool menu and select Settings.
We need the “Content” block, it is third on the list.
Visit it, check the box next to “Use JavaScript”.
Confirm the action using the “OK” button.

Yandex browser

The domestic project requires spending a little more time navigating to the control menu.

Visit the “More” submenu, shown as three lines.
Rotate the window that opens to the very bottom until you come across “Show advanced settings”.
Get to "Personal Information". Select Content Settings.
There is a section dedicated to Javascript, in it you need to check the box next to “Allow JavaScript on all sites”.
All you have to do is click “Finish”.

If necessary, the script can be configured for individual Internet resources; all you need to do is devote a little time to the “Exception Management” settings.

Opera

Everything is as simple as possible here:

Visit the Settings section.
Immediately go to the “Advanced” tab and switch to the “Contents” item. Next to “Enable JavaScript”, check the box.

Conclusion

It is quite simple to enable any of the Java languages; it is only important to understand the settings of web browsers.

VKontakte website does not open
DEC192009

IN Lately Many people have problems accessing certain sites, such as yandex.ru, google.com, odnoklassniki.ru, vkontakte.ru, and also letters on mail.ru do not open. If you are reading this, it means that, most likely, the VKontakte website also does not load for you, or a window appears in which you are required to send an SMS to unblock the site. There can be many reasons, so I will try to describe them all in detail, and also tell you how to eliminate them.
We fix it HOST file
One of the most common problems due to which the VKontakte website does not open is the vulnerability of Windows, or rather one of its files - HOSTS, which converts domain names into the corresponding IP addresses. This file is often used by viruses that add additional lines there. On Windows XP and Windows Vista file located at:
WINDOWSsystem32driversetchosts
Myself clean file HOSTS looks like this:
# Copyright © 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
#space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a "#" symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
It may also be in the Russian version, but that doesn't matter. Open this file with any text editor(right-click on the file, then “Open with” and select notepad, for example) and if you see that your HOSTS file does not look right, then you need to fix it by deleting everything unnecessary. It happens that the HOSTS file cannot be changed because it is locked malware. In this case, you will have to correct it in safe mode. In order to boot the computer in safe mode, reboot it and press the F8 key while loading. A window with boot options should appear, in which we select “Safe Mode”.
Important: Do not forget that the HOSTS file does not have an extension; it should not be called, for example, HOSTS.txt.
For users of pirated Windows versions The HOSTS file may be duplicated in another folder on the computer, so I advise you to use the search to find it.
Delete the files svc.exe and vkontakte.exe
It also happens that the VKontakte website is blocked by malware. These programs need to be removed. Go to Start -> Search -> Files and folders -> Extra options-> Put a tick next to all the items (search in system files, hidden, etc.) and look for the files svc.exe and vkontakte.exe. If you find it, delete it.
After each method, you must restart your computer, and only then check whether you can access the VKontakte website or not. Be sure to install the latest antivirus software software and update antivirus databases, and then check your computer, otherwise, after some time, you will have to correct the HOSTS file again.
In addition, you can also try accessing the VKontakte website through the vk.com domain; this simple action has helped many.
And one more piece of advice - never download various programs for Contact (view personal messages other users, viewing closed pages, programs for downloading music from a contact, etc.) because most of them contain viruses, be careful. And also don’t forget to change the password for your page.
If the above methods did not help, then try reinstalling Windows.
