Frequently asked questions

What is a bookmarklet?
A bookmarklet is a browser bookmark whose URL is JavaScript code starting with javascript:. Clicking it runs the script on whatever page you are viewing.
How do I install the generated bookmarklet?
Drag the generated link to your bookmarks bar, or right-click and choose add to bookmarks. From then on, clicking it runs your script on the current page.
Why do modern sites sometimes block bookmarklets?
Strict Content Security Policy headers can prevent inline scripts from running on some sites. There is no workaround from the bookmarklet side, but most pages still allow them.
