When using Internet browsers to watch videos or animated images, or run Flash games, a situation may arise when the plugin required for this is not supported.

And this situation does not depend either on the speed of network access or on the power of the PC - only on the software.

A plugin is an add-on that adds additional functionality to an application.

However, it usually does not come immediately with the program, but is installed as needed. Sometimes installing one multi-platform plugin is enough to ensure the work of several browsers at once.

Finding out the cause

First of all, after the message about the lack of plugin support appears on the screen, you need to find out why this situation arose.

Sometimes an image that resembles a puzzle piece or another picture indicates that a software add-on is not installed.

There may be several options:

• The browser or its specific version does not support the required plugin. Thus, the outdated Firefox 4 is not able to reproduce some add-ons. On the contrary, the Chrome Java plugin is not supported by the latest versions of the browser since April 2015;
• An error has been detected in the add-on code, causing it to not work properly. This often happens when an already proven browser and plugin are installed on a new version of software (for example, from Windows XP to Win 7 or 10).

Options for resolving the issue

The issue should be resolved according to the problem that has arisen - that is, either by updating the browser or installing a more modern version of the plugin.

However, most browser add-ons made on the Java platform have vulnerabilities and problems with updating - and some of them are better not to install at all.

For example, the same Flash Player, in order to increase the security of a particular browser, can be launched separately, as an application.

1. Browser update

When deciding what to do with an unsupported plugin, and considering reinstalling the browser as an option, you may encounter the following problem:

• the required application does not support the required add-on;
• Replacing an old browser with a new one is unacceptable due to some functions that are more convenient in this version.

In this case, you can try to leave the old browser for logging into the network, installing a new one for those actions that require a plugin.

2. Replacing the Java plugin

Replacing a browser add-on with a new one may not always help if you still have an outdated Java client on your PC. The plugin will work, but not for long. After some time, malfunctions may occur again, which means the need to update Java.

Important! You should only look for installation files for your system on the official website. Otherwise, you can download not only software, but also viruses.

The procedure for downloading and installing Java is quite simple, which means that any user can do it independently. Although this will take some time and require a restart of the computer.

3. Flash Player plugin

Most often you encounter the need to use a plugin:

1. Users of social networks, where you can often find browser applications and games that require a special add-on to launch;
2. People who watch movies online in a browser.

Advice! You should only look for the Flash Player version to install on your computer on the manufacturer’s official website. However, the same applies to other plugins.

To install the add-on file:

1. Go to Flash Player Adobe page;
2. Download the program;
3. Perform the installation after closing all browsers.

Adobe's download page may automatically include a checkbox for installing additional programs, such as Chrome or McAfee antivirus. If you do not remove it, these applications will be downloaded and installed along with the plugin.

Although, if your PC does not have Chrome or an antivirus, you can install several useful programs on your computer at the same time.

The need to close Yandex.Browser and other applications used to access the Internet during the installation process is caused by appropriate changes being made to them. After all, the installed Flash Player plugin will work on all browsers.

In order to encounter this problem as rarely as possible, you should regularly update the plugin.

If the user works with the Mozilla browser, there is a special service to check the relevance of Flash Player, by going to the page of which you can find out about the need to install a new add-on.

Other plugins

In some cases, when using specialized plugins that allow, for example, logging into a specific site through a proxy server, the browser may also not support their operation.

Most often this happens due to an outdated version of the software and requires replacing it with a new one. It is also possible that the site owner simply stopped supporting the plugin, and you will have to access it in another way.

Large companies that produce browser add-ons usually do not have such problems. Extensions are supported for a long period of time, and discontinuation is announced in advance.

conclusions

Solving the problem with an unsupported plugin will take a little time from the PC user.

But after updating or reinstalling all applications, you won’t have to deal with it for a long time - especially if the cause was an outdated browser, which has already been replaced with a new one.

Hello, dear readers of the blog site. In simple terms, then plugin is an add-on(extension of capabilities) for any program on your computer or website engine on the Internet. It is very difficult for developers to provide for all the wishes of users, so they give the opportunity to third-party developers to satisfy these wishes by writing plugins (from the English plugin).

In addition, if all possible things are provided in one application, then it will become very heavy and clumsy, but thanks to plugins this does not happen, because each user receives basic functionality, and he can get everything else by downloading or installing the extension he needs.

What are plugins in simple words and where can I download them?

By the way, some plugins themselves can even remind you that they should be installed. Do you know such examples? For sure. Everything is the same when its presence is necessary to play video content on an open page.

So let's recap, what are plugins? In general, this is a software block that can be installed (connected) to the main application to expand its functionality (adding new features). Please note that not every application has the ability to install plugins - it must provide this. As a rule, the plugin itself (without this application) cannot work.

If we draw parallels and take this publication as an analogue of an application, then your comments, dear readers, can be equated to plugins. This “application” allows you to do this using the form for adding a comment, just as the real program offers the software add-on a data exchange protocol. Without this form, you will not be able to leave your comment, even if you wish.

Continuing the analogy, we can come to the conclusion that only those applications that are popular and capable of gathering a huge number of users and interested plugin developers around them acquire a large number of extensions. Likewise, my article will be able to collect a large number of comments only if it is highly popular, relevant and topical.

Where to download the plugin you need for each specific application, you can find out on the official website of this program or website engine. Enter the name of the application in Yandex or Google, and the first site in the organic results will most likely be official.

This is very relevant because through unofficial plugin A virus has a chance to sneak onto your computer or website (its signature may be contained in its code or it may crawl through a hole that the developer did not notice). It’s not for me to tell you how difficult it is to clean your computer afterwards, but I described it in some detail. In any case, it takes a lot of energy and nerves.

Let's take a look at the most striking examples of plugins for various applications (browsers, programs and website engines) so that you better understand what we were talking about here and how useful certain plugins actually are.

Plugins for browsers and other programs on your computer

Let's start with browsers. The founder of the use of third-party software blocks to expand the functionality of the browser was, of course, . Actually, his enormous current popularity stems from the fact that he was the first to introduce the idea of ​​expanding functionality to infinity with the help of plugins and managed to score a lot of points on this before his main competitors thought of repeating his experience.

For such a popular program in RuNet as Photoshop, there is also a very rich assortment of add-ons, which, however, are not called plugins, but filters, but the essence does not change. Everything that is not included in the functionality of the program can, if desired and with some luck, be implemented using plugins.

For example, saving a graphic file in a format that is not initially supported (ico, for example). Installing filters is not difficult and you can read about it on thematic resources.

Plugins for website engines using the example of WordPress and Joomla

For webmasters, plugins are also associated with extensions for those (site engines) that they are used. According to statistics, the most popular free ones are Joomla and WordPress, so we’ll talk about them now.

The WordPress engine allows you to create blogs, and in terms of functionality and ease of use it is quite capable of competing with paid solutions. However, you will hardly find a blog that does not use at least one plugin. No matter how rich and varied the capabilities of the CMS itself are, there is always something that needs to be implemented, but cannot be done without additional extensions.

At the same time, I only use free extensions, which is doubly nice. Download plugins for WordPress you can from the official website (so they are checked for viruses and other nasty things) or directly from by going to the tab from the left menu “Plugins” - “Add new”.

The components of them are the most voluminous and sophisticated, and the modules are used to display content around the perimeter of the site (above, below or to the side of the main content). A plugin in Joomla is a special product that can, for example, react to any events and does not have such rich settings as a component.

Vivid examples include: plugins for Joomla, like , and a number of others that are installed in it by default. Among the components are the following:

I hope that in general terms I was able to explain what plugins are, and you also remember that they can only be downloaded from official sites, or installed directly from the program or the admin panel of the site engine. And so, a wonderful thing, without which our world would be much poorer and less usable than it is now.

Good luck to you! See you soon on the pages of the blog site
