Why I can’t launch the extension in Yandex browser and methods to solve the problem

Modern programs are very “smart”, but sometimes they fail, which are preceded by a lot of reasons, ranging from physical to software. In the Yandex browser, the error most often appears is “could not load the plugin,” this indicates the absence or disabled state of a separate module. This problem applies exclusively to Adobe Flash Player, as it occurs when trying to play a video or animation. Various reasons can cause a plugin to fail to load, but they are all fixable. We will tell you how to troubleshoot the problem in the article.

The key reason why the plugin could not be loaded in the Yandex browser is a malfunction of Adobe Flash Player. It is a built-in module in Chromium-based browsers: Opera, Google Chrome, Yandex Browser. You can find the plugin in the section browser://plugins called Adobe Flash Player with the signature Shockwave Flash. The user himself does not have much influence on the add-on settings; the only thing he can do is turn off or activate the module.

Among the common reasons why Adobe Flash Player malfunctions, we highlight:

  • The plugin is disabled in the settings. This is the simplest and most common reason why the plugin does not load in the Yandex browser. To fix it, just change the launch parameters in the settings;
  • Browser malfunctions due to cluttering with temporary files: cache, cookies, history;
  • Outdated browser. Each program has a lot of shortcomings, which the developers are gradually eliminating. Only in the latest version of the browser are there the least risks of encountering defects;
  • Viral activity in the system. Viruses can damage some of the functions of any program and Yandex browser is no exception;
  • Launching the plugin blocks a third-party extension.

Each problem has its own solution, but some methods are universal and suitable for almost all users. One of the universal methods is system recovery.

How to fix the problem - the plugin could not be loaded?

Launching the plugin

If the message “could not start the plugin” appears in the Yandex browser, the first thing we recommend is to check the activity of the module. Many users disable Shockwave Flash on their own, since with its help sites reveal the location of the computer, bypassing anonymizers. To increase anonymity, it is recommended to disable Adobe Flash Player, but without it, individual videos will stop loading.

Checking the plugin activity:


Clear cookies, cache, history

Before moving on to other methods to restore your browser, you should clear all third-party files. This can be done within the browser itself in one of two ways: using hot keys or through the settings section.

Standard way to clear history:


An alternative way to get to the right place is to click Ctrl + Shift + Del. The next steps are identical.

If extensions in the Yandex browser do not work for this reason, after cleaning and restarting the browser, the videos will start running normally.

Browser update

If Yandex Browser shows an error while viewing media content, there is a possibility that the problem is in an outdated version of the program. The likelihood of this problem is especially high if the Yandex browser stops loading for no apparent reason (In this case, reinstalling the browser is necessary).

How to update your web browser:

Virus cleaning

It is extremely difficult to manually detect viruses and their consequences, but there are special anti-virus programs that will do this for us. The first option for cleaning the system from viruses is to run a deep cleaning procedure in an antivirus: Nod32, Kaspersky, etc.

To avoid installing an antivirus, you can install antivirus scanners, which do not protect your computer in real time, but only scan Windows and remove viruses. They do their job quite well. One of the best options is Dr.Web.

If the video is not shown due to the influence of malicious code, simply removing viruses is not a sufficient procedure to restore functionality. Often you have to reinstall the Yandex browser completely.

Checking extensions

Some extensions like “Disable Youtube™ HTML5 Player” can block Adobe Flash Player by switching to HTML5. If the browser or resource does not work with the HTML5 standard, a characteristic window will appear indicating that the plugin could not be loaded.

You should check for the presence of such extensions:

To shorten the time, you can press Ctrl + Shift + N and try running the video in incognito mode. Add-ons in incognito mode are inactive without manual configuration.

Additional recovery methods

If the Yandex browser has stopped loading videos and shows an error even now, this is not a reason to refuse to use it, because there are several more proven methods:

Unfortunately, there are still cases where certain browser functions do not work, but now one of the problems - “could not load the plugin” in the Yandex browser - can be considered resolved. The listed methods help in 99% of cases.
