Would you like to see other CDN or versions (e.g. jQuery or Bootstrap) integrated? Feel free to open an issue or pull request.

Donations are possible. The possibilities for donations can be displayed in the extension. (Reduces traffic and prevents your IP from being listed in the server logs. Therefore a small offline help page is also integrated.)

For clarification: This extension doesn't create an external connection by itself. LocalCDN contains these frameworks/libraries in add-on storage. This is the reason why the size of LocalCDN is 17 MB. There is also a donation page and a short FAQ page inside the extension. There are only external connections in the form of hyperlinks that the user must actively click on. This includes, for example, the test page or the translation platform "Weblate". All links are marked.
