If you are sure that you have the Adobe Flash Player plugin installed on your computer, However, when you open a web page, you will still be prompted with “Adobe Flash Player plugin is blocked”. You can change the following two options to no longer indicate that the plugin is blocked
1. Open the chrome: / / Settings/content, the Adobe Flash Player plugin Settings changed to “allow website run Flash”. If the Adobe Flash Player plugin is still blocked, go to the second item. If you are no longer prompted that the plug-in is masked, try not to change the Settings of item 2.
2. Open Chrome ://flags/#run-all-flash-in-allow-mode to enable this option.
