Preparation

First of all, ensure that you have indeed downloaded Adobe Flash and installed it properly on your Windows computer and updated it to its latest version. If you are using Internet Explorer on Windows 10/8, then Flash has been integrated, and its updates are offered automatically by Windows Update.

Enable Flash Player in Chrome for a Website

Navigate to browser's search bar, and click the site settings button.

Use the "Settings" button to find the Flash settings.

Switch to "Always Allow for the website" option.

Reload the webpage.

Enable Flash Player in Chrome

Open your Google Chrome browser. The chrome://plugins page was removed in Chrome 57 and later. So now you have to use chrome://settings/content/flash to control when Adobe Flash content is loaded.

To check the Adobe Flash Player version installed type chrome://components.

Enable Shockwave Flash Object in Internet Explorer

To check if your Flash Player is enabled by Internet Explorer, from the top right corner open Settings > Manage Addons > Toolbars and Extensions.

Here, ensure that Shockwave Flash Object is Enabled. Flash Player is also referred to as the Shockwave Flash Object.

Enable Shockwave Flash in Firefox

From your Mozilla Firefox menu, select Add-ons.

Under Plugins, select Shockwave Flash. From the drop-down menu, select Ask to activate, Always activate or Never activate, as you desire.

Disable Adobe Flash in Opera

Open Opera Menu. Select Manage Extensions. Here you can click on the Enabled link and Disable the Flash Player. To Enable it, you may check under the Disabled link.

In Opera 45 and later versions, if you have enabled the left Sidebar from Opera Menu, you will see the cube-shaped Extensions link. Click on it to open the Extensions page. Here you can see all the Extensions.

Turn on Adobe Flash Player in Microsoft Edge browser

To disable or enable Flash Player, open Microsoft Edge, click on the three-dotted button and select Settings.

Scroll down to the bottom and select View advanced settings.

On the next page, you can find an option called Use Adobe Flash Player. Toggle the button to turn it on or off.
