Disable browser plug-ins

During web development and testing, sometimes it is necessary to test whether the plug-in is disabled or not installed. This setting is quite hidden.

For example, after disabling the flash player plug-in, is the user experience good?

Take my favorite QQ browser version 9.5 with built-in IE5, 6, 7, 8, 9, 10 as an example:

Settings->Advanced Settings->Security and Privacy->Content Settings->Plug-ins->Manage various plug-ins

Then search for flash player and you will find common Thunder plug-ins, iQiyi plug-ins, pplive plug-ins, etc.
