What is a Bookmarklet?

"A bookmarklet is a bookmark stored in a web browser that contains JavaScript commands that add new features to the browser. They are stored as the URL of a bookmark in a web browser or as a hyperlink on a web page. Bookmarklets are usually small snippets of JavaScript executed when user clicks on them. When clicked, bookmarklets can perform a wide variety of operations, such as running a search query from selected text or extracting data from a table." - Wikipedia

Bookmarklet Reference

Quick reference for the labels and indicators used throughout the bookmarklet table.

Active

An Active bookmarklet makes additional web requests — it contacts the website's servers or a third-party API to fetch data beyond what is already loaded in your browser. Because it sends network traffic, the target site may log or detect its use.

Passive

A Passive bookmarklet only reads and processes data already present in your browser — it never sends additional requests to external servers. It extracts information from the page source or existing browser memory without leaving any additional network trace.

🚨 Recent Date Indicator

Several bookmarklets highlight dates that fall within the past 7 days with a 🚨 red siren indicator. This is a visual alert to draw your attention to very recent account activity, post dates, or timestamps — which may be significant in an investigation. The indicator appears inside the bookmarklet's popup window next to the relevant date; it does not affect the underlying data in any way.
