When you want to install a program or application, the software installers themselves will ask if you want to add an add-on, or rather, a plug-in. Most of the time, users just accept to finish the installation quickly, but we\'ll explain what it\'s for and whether you can fully trust its installation. There are different types of plugins. On the one hand, there are some specifically for audio and video playback programs. On the other hand, you can find add-ons for web browsers, an example of which is Ad Block, to block any advertising on the screen you\'re using. Plugins are used as extensions that allow you to connect functions to the default browser, offering users other options or tools for a better user experience. As for music playback plugins, they can be used for playing DVDs or Windows Media Player; the software itself may offer this capability in the Microsoft operating system. Some examples of this might include a plugin being used as an external CD that could not be installed due to your console\'s limitations. You should also be aware that there are other types of plugins whose objective is to steal your browsing data or otherwise attempt to install malware on your computer. To avoid this, use open-source plugins and download them from official sources. Additionally, pay attention to the permissions they request, especially if they request camera access and the plugin\'s permissions are inconsistent with your existing access settings. The first plugins in history began appearing in 1970, when the EDT text editor, running on the Unisys VS/9 operating system and using the Univac 90/60 series of computers, allowed an external program to access memory to edit the session. In 1987, Macintosh incorporated this functionality into HyperCard and QuarkXPress. And in 1988, Silicon Beach Software included plugins in Digital Darkroom and SuperPaint, and Ed Bömke coined the famous term \"plug-in\".
