Add-on summary

Analyze keywords

JSLibCache

A WebExtension for Firefox / Chrome that enhances privacy by serving requests to popular CDNs from local cache/storage. It is similar to Decentraleyes / LocalCDN. It serves Javascript libraries, CSS files and Fonts that a website tries to load from popular CDNs like ajax.googleapis.com.

Difference between JSLibCache and Decentraleyes / LocalCDN JSLibCache fetches resources from CDNs dynamically, once. So if a website you visit requests https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js and that lib is not yet in the local cache, it is fetched from the CDN and put into local storage for subsequent requests.
