Insert a code snippet in one line as a bookmark:

javascript: (() => {
// Code here
})();

For example:

• Find a "Jobs", "Careers" or "Hiring" link in the page, and click it.
• Find all email addresses on the current page, and display them in an alert.

These are not limited with permissions, so we should only execute code we checked.

#idea #project a collection of bookmarklet

Simply run these scripts on the web page to trigger some actions.

• Validate HTML
• Calculate carbon
• WAVE
• PageSpeed
• SSL Report
• Security Headers

They're nice and useful tools :)

They can be extended to browser extensions if they need to.
