NoScript is an add-on that can disable JavaScript on web pages, put limits on the types of JavaScript permitted, and block known attacks.

The downside is that setting those options is an all-or-nothing deal. The advanced features are either always allowed or always prohibited. NoScript lets you allow JavaScript on websites that you trust and block JavaScript on all other websites. That puts the power in your hands. You just need to be careful not to trust too many sites; otherwise, this add-on won’t provide much protection.

uMatrix put you in full control of where your browser is allowed to connect, what type of data it is allowed to download, and what it is allowed to execute. Nobody else decides for you: You choose. You are in full control of your privacy.

These firewall options show up as a colored red-and-green matrix and all you have to do is click on the features you want to toggle. It’s a bit more advanced than a straightforward blocker, but the steeper learning curve allows for more power and flexibility in the end.

Most websites consist of HTML show the structure of a website. Together with CSS for styling, and JavaScript for interactive functionality, the website can provide value for its visitors. Some of the used JavaScript libraries are heavy on bandwidth, so website owner may use a content delivery network (CDN). The primary goal for a CDN is to get data closer to the end-user, which results in faster downloads and increasing the performance of the website.

Some common JavaScript libraries are used on many websites. As not every single website creator can pay the costs of a CDN, bigger companies might actually sponsor bandwidth on their CDN edge servers. While this is great from a cost perspective, it also introduces a privacy concern. The owner of the CDN can exactly see what websites a user is visiting by looking at the related requests to the CDN and the related referrer. This is where Decentraleyes comes into place, by intercepting requests to content delivery networks (CDN).

Decentraleyes looks into the returned HTML data. It replaces external requests to CDNs if it discovers a known JavaScript library. This way the CDN never receives the request. It actually may increase the speed of some websites, yet the main benefit is increased privacy.
