Consent-O-Matic is an open-source extension that was built and maintained by Aarhus University in Denmark. While it offers protection against violators of the EU's General Data Protection Regulation (GDPR), it also works well globally.
Browsing the internet and being constantly bombarded by requests for cookies can get frustrating. There are some reasons why you might want to use cookies and deal with pop-ups. You may want targeted ads and to get better suggestions for your streaming options. You may also not want to type in passwords and usernames every time you visit a website.
While cookies can be good, some people get bothered by them. Many times, they are meant to store data from a user's browser. Sites want to track users to serve them better. But there are plenty of sites that will do negative things, such as tracking users' data and potentially leaking it to third parties. There's a lot of malicious intent and security vulnerabilities that can come from sharing the wrong kinds of cookies. That's why I use Consent-O-Matic, a browser extension that eliminates me having to deal with any cookie pop-ups that I don't want to.
