If you get a "A plugin is required to display this content" error in Firefox when you try to play a video, you'll need to install the Mozilla Flash plugin or, if you have one, check its settings. Also, this applet is required in Mozilla not only for watching videos, but also for launching browser games, displaying animated banners and various interactive elements on web pages.

Until recently, a similar notification was displayed even if there was no Java plugin. But, starting from version 52, FF no longer supports it, as well as other NPAPI modules (Silverlight, Adobe Acrobat). Their functionality is provided in the web browser by other software solutions.

This article will help you add the missing video plugin to Firefox, and will also tell you what operating mode you need to set for it.

Installation

1. In Firefox, open the plugin’s website - https://get.adobe.com/ru/flashplayer/.

2. Make sure that the first block shows your PC configuration (browser and system).

3. In the next block, click to uncheck the boxes so that additional programs are not installed on the system along with the plugin.

4. Click the “Install…” button.

5. When the download is complete, click the “down arrow” icon at the top right.

6. In the window that pops up, click the “folder” icon.

7. Right-click on the installer. Select "Run as administrator..." from the menu.

8. Allow installer access: click Yes.

9. If necessary, change the plugin update mode. Click “Next”.

10. Wait for the installation to complete.

11. Restart your browser.

Debugging the plugin

If Flash is installed in Firefox but isn't working, try the following:

1. Press the "Menu" button (the "three stripes" icon at the top left).

2. In the panel, select Add-ons.

3. In the plugin line, check the launcher addon. The optimal value for frequent playback of media content on web pages is “Always on”.

Perform a Flash update:

On the add-ons tab, click the gear icon. From the list, select “Check for updates.”

Or download the update through the Windows Control Panel:
1. Open: “Start” → “Control Panel”.

2. Click the “Flash Player...” icon.

3. In the “Updates” tab, click “Check Now”.

Try disabling add-on filters:
1. On the “Add-ons” page, in the “Shockwave Flash” block, click “Details”.

2. In the options “Block dangerous...”, “Enable protected mode...”, uncheck the boxes.

If none of the above methods work, try playing the video on the web page in a different browser.

If an error is displayed after setting the appropriate settings in Firefox, remove Flash from the system, download its new version from the website and reinstall it. Additionally, check the network rules in the firewall: whether network connections are allowed to the Flash plugin.

Mozilla Firefox is one of the most popular browsers for the Windows operating system. It has its advantages over Google Chrome, Opera and other applications for browsing the Internet. As with all other browsers, various problems can occur with Mozilla Firefox that will prevent the user from accessing the desired page on the Internet. If one of the errors that may occur during the page loading process, the user will see a notification “A plugin is required to display this content.” In this article, we will look at why this error occurs and how to fix it.

Why does the error occur?

Website pages on the Internet can be built in various ways, including using plugins from well-known developers. Most often, third-party plugins are needed to implement interactive elements or videos on a website. If the necessary plugin for working with content on the site is not installed or activated in the browser, the error in question will occur.

“A plugin is required to display this content”: what to do

Solving the problem with the lack of a required plugin in Mozilla Firefox is quite simple - you need to install it or activate it if it is disabled. To enable the required plugins to display content on the site, you must proceed as follows:

Important: If next to a plugin that you need to enable you see a message that it is vulnerable and requires an update, be sure to update the plugin from the official developer website. The fact is that creators are constantly eliminating vulnerabilities in their software, which is why it is important to keep plugins up to date.

It is possible that in the list of Mozilla Firefox plugins you will not see Java and Shockwave Flash or one of these plugins. In such a situation, you will need to download their latest versions from the official developer sites and install them on your computer. Don't forget to restart Mozilla Firefox after installing the plugins for the changes to take effect.

What to do if plugins in Mozilla Firefox are disabled by themselves

The browser user must configure the plugins necessary for operation once, after which they will be enabled automatically each time. If plugins in Mozilla Firefox are disabled by themselves every time you exit the browser, you need to scan your computer for viruses. To do this, you can use free antiviruses, for example, AdwCleaner and Dr.Web CureIt!. It is recommended to scan with both antiviruses.

If an antivirus scan does not help solve the problem and Mozilla Firefox continues to disable plugins by itself, make sure that the latest version of the browser is installed on your computer or uninstall the program and install its latest version from the official developer website.

Any user can push it. Even the most careful and pedantic person who monitors updates of important programs for his personal computer is not immune from errors in the system or incorrect operation of a particular utility.

If Flash Player doesn't work in Firefox, here's how to fix it:

Go to the official technical support website for Adobe products and look in the “Flash Player Help” section.

In the new tab that opens, an easy-to-understand description will appear in five steps for checking and installing the required module.

Step one is to check that the Adobe Flash Player software is up to date. If everything is fine, a similar sign will appear; if not, the appropriate information will be displayed.

The second step, if there are problems, is to install Flash Player on the user's personal computer. To do this, you need to follow the appropriate link.

The third step will be the installation of the program itself.

Step four is to activate the plugin. The developers' website provides detailed instructions for the most popular search engines for both the Windows and Mac OS operating systems. Recommendations for Mozilla Firefox are similar to those for Google Chrome and Opera browsers. If you learn how to fix such errors in one Internet browser, there will be no problems with others.

To do this, you need to go to the settings menu in the “Add-ons” section, then to the “Plugins” tab and make sure that the “Shockwave Flash” module is present and active.

Also useful are two features for blocking dangerous and intrusive Flash content and additional protection from Adobe. By clicking on the “More details...” links you can familiarize yourself with the advantages of these two functions.
