What is a plugin? What is it used for? A plugin is a piece of software that acts as an add-on to a web browser and gives the browser additional functionality. Plugins can allow a web browser to display additional content that it was not originally designed to display.
What is a plug-in?
Plug-ins are small additional programs that extend the functionality of web applications and desktop programs. If you install a plug-in, the respective software usually receives a new function that it did not have before. Most users are probably familiar with plug-ins for web browsers. For example, if you want to view documents in PDF format, you must first install a plug-in for Adobe Acrobat Reader (or another PDF program), otherwise the browser cannot process the data.

Are they foolproof?
It's like almost everywhere on the Internet, there are also dangers lurking. Hackers have discovered vulnerabilities and in this way try to infiltrate software on the user's computer. So be careful, this applies to plug-ins as well as to any use of the Internet. Perhaps it will be useful to compare it with your own apartment, in which you feel comfortable, relax, but also keep all your certificates and important valuables. It would never occur to you to leave the door open for everyone to enter and look around.
What can you do about the danger?
They often signal themselves when they need an update. But you should regularly check if the plug-ins you have installed in your browser are up-to-date. Also, it is important to download plug-ins and security updates only from the manufacturer's original website, so that you don' t end up with a fake, possibly infected version.
